动三轴试验过程的误差分析
Error Analysis of Dynamic Triaxial Test Process
 [PDF]


Hans Journal of Civil Engineering (HJCE) , 2013, DOI: 10.12677/HJCE.2013.22017
Abstract:
动三轴试验是室内土工试验中研究土体动力特性的重要方法,但从试验结果来看具有一定的离散性。这既有试验操作者的人为误差,也有动三轴仪系统本身带来一定误差,如试样制备过程中的误差,系统本身的阻尼力,试验数据的滞后性等等。为了更好地改进和利用动三轴试验研究土体动力特性并解决相关实际问题,有必要对动三轴试验全过程的误差进行分析,提高动三轴试验的准确度。
Among indoor soil tests, dynamic triaxial test is an important method in the study of dynamic properties of soil but with certain discrete in test results. Both the test operator and dynamic triaxial system itself bring some errors, such as errors in the sample preparation process, the damping force of the system, the lag of the test data, and so on. In order to improve and use dynamic triaxial test better for soil dynamic characteristics and solving practical problems, it is necessary to analyse errors in the whole process of dynamic triaxial test and improve the accuracy of dynamic triaxial test.

This article is the summary monograph content of the author’s patent of Cold Fusion Reactor[1] and the monograph of New Modern Physics[2]. We expect to do academic exchanges with mainstream fusion of modern physics and engineering academia. This monograph is based on Einstein’s idea of determinism; it first creates a classic elementary quantum spin fluctuations vertical double elliptical orbit motion model, which is combined with Newtonian mechanics, the basic equations of motion electrodynamics, quantum mechanics, elementary particle velocity along the track combined with the relation between the energy, and which is deduced and solved using unified self-consistent mathematical physics equations. It can accurately answer all the elementary particles, nuclei, the internal structure of the atom, composition, movement characteristics, law decay reason, energy, quality source of strong, weak and elec-tromagnetic interaction between and intensity of the interaction; and it can also answer the propagation medium and principles of the microscopic, macroscopic electromagnetic field and gravitational field. We eventually demonstrate the infinite eternal cosmology, absolute time and space and a large unified field.

Abstract:
在实际工程设计中,多数结构工程设计人员并未重视高层建筑结构嵌固端的选择。这样往往会造成材料浪费,也会给高层建筑结构留下隐患。对于高层建筑结构嵌固端的定义,部分结构设计人员也存在误区,认为是力学嵌固,其实应为强度嵌固。规范对地下一层顶板作为嵌固端明确了要求。本文对三种地下室平面面积型式不同的高层建筑结构嵌固端做了初步的探讨,得出了一般情况下,不同地下室平面型式嵌固端的位置,并得出了地上一层与相关范围地下一层侧向刚度比是衡量地下一层顶板能否作为高层建筑结构嵌固端的关键。
In the practical engineering design, structural engineering staffs did not attach importance to fixed end of high-rise building structure. This will cause material waste, and will also leave hidden troubles to the high-rise building structure. Some of the structural designers have mistakes in the definition of fixed end of the tall building, who regard them as mechanics embedment, but in fact it should be strength-mounted. Specification makes requirements clearly about the roof of the underground layer as embedding end. In this paper, three basement flat area types of high-rise building structure embedded end have been studied. It comes to conclusions 1) there are different embedding positions in different basement flat forms under normal circumstances, and 2) the lateral stiffness ratio of ground floor with the relevant range of underground floor is the key to measure whether the basement roof can be used as a high-rise building structure embedded fixed end.
张应力放大系数矩阵—岩体无张力分析的捷径

岩石工程学报 , 1986,
Abstract: 为模拟岩石的无张力性质,晋基维茨(zienkiewicz)曾建议并且采用“应力转移法”进行无张力分析。任何应被减少的张应力经过一个迭代过程之后就可被近似地消除。迭代所进行的次数必须持续到张应力全部被消除(近似的)为止。本文给出了一个仅需一次迭代就可消除(精确地)张应力的矩阵。将应减少的张应力乘以该矩阵之后仅需进行一次迭代就可达到“应力转移”的目的,大大加快了系统的收敛速度,节省了应用“应力转移法”进行无张力分析所耗费的大量计算机时。
桩侧摩阻力计算的简单数学模型

岩石工程学报 , 1986,
Abstract: <正>划分桩侧摩阻力和桩端承力对单桩的计算具有重要意义,也是分析桩荷载传递机理的基础、是确定摩阻力和端承力的前提。国内外对这一课题已有多年的研究,解决的方法基本上有两类:一类是应用触探仪。如荷兰锥等,通过探测土层的物理参数与试桩资料对比,以建立经验公式或修正曲线,从而来划分桩侧摩阻力和桩端承力;另一类方法是通过桩静载试验

Abstract: 塔里木河各源流的径流规律不完全一致,导致了塔里木河干流水源组成变化比较大。为了认识塔里木河流域的源流和干流径流规律的特点,为流域的水资源可持续发展提供依据,采用模比系数Kp值法、Morlet小波分析法、坎德尔(kendall)秩次检验法分别对塔里木河源流和干流阿拉尔站(1958~2007)年径流的丰枯变化、周期性、趋势性展开分析,经计算分析,塔里木河源流和干流丰枯同步频率为26%;周期尺度表现相对一致,存在17年的周期成分,径流趋势呈现不同,源流有增有减,干流则递减。

To analyze the runoff rules of Tarim River’s headwaters and trunk stream, and provide the basis for sustainable development of water resources, this study selects modulus coefficient Kp method, Morlet wavelet analysis method and Kendall rank test model to analyze the abundance, cycle and trends annual runoff rules of headwaters and Alar hydrological station (1958-2007) at main stream of Tarim River. The results show that, the frequency synchronization of abundance of headwaters and main stream is 26%. The existing cycles is 17-year cycle, the runoff trend of headwaters are increasing or decreasing, while decreasing at main stream.

Abstract: 水库调度图作为指导水电站安全高效运行的依据,一直是水库调度研究的热点,然而现有研究大多以单库调度图为对象进行优化,或是基于中长期发电优化调度模型绘制梯级水库调度图。单库优化调度图较难满足梯级调度要求,而后者虽然理论成熟、应用广泛,但存在建模、求解复杂,步骤繁琐,误差较大等的缺点。鉴此,本文提出了一种采用模拟与优化相结合的技术绘制梯级水库优化调度图的实用方法。该法通过直接优化梯级水库常规调度图的调度线,从而获得优化调度图。以乌江流域4座调节性能较好的水库构成的梯级水库为研究对象进行实例分析,模拟调度结果表明较大地提高了梯级长期发电效益,验证了该法的可靠性和有效性,从而为梯级水库优化调度图的绘制提供了新思路。
Reservoir operation chart has been a hot topic of the reservoir operation study as a basis for the guidance of the efficient and safe operation of the hydropower station. However, existing studies are mostly studying on the optimizing drawing of single reservoir, or research on the drawing of cascade reservoirs operation chart using a long-term power optimization scheduling model. Single reservoir optimized operation chart is hard to meet the cascade scheduling requirements, while the latter theory is mature, widely used, but has its flaws. For this, this paper puts forward a drawing way of cascade reservoirs optimal operation charts, using the combination technology of simulation and optimization, through the direct optimization of the cascade reservoirs conventional operation curves. For the cascade hydropower stations on the WujiangRiver, simulation scheduling results show considerably increase on the cascade long-term generation benefit. Thus verify the reliability and validity of the method, so as to provide a new idea to draw the cascade reservoirs operation chart.
柔性多肽片段–蛋白质相互作用的全局对接方法

Abstract:
多肽–蛋白质的相互作用在生物细胞中发挥着各种各样重要的作用。通常情况下,它们之间的结合信息是未知的。所以,利用计算方法预测结合位点具有重要意义。而以Rosetta为代表的常用对接软件通常具有很强的初始位置依赖性。为克服这一局限性,本研究提出了一种全局对接的方法,以受体蛋白为球状系统的中心,将多肽平均地分布在球面26个位置上;同时定义了一个区分天然结合构象和非天然结合构象的筛选参数。用上述方法预测多肽–蛋白质的结合构象,结果显示该方法能成功预测蛋白质的结合位点,且多数多肽的预测构象的Cα-RMSD在5.5 ?以下。因此,研究结果表明,所发展的方法在蛋白质多肽结合位点预测方面有很好的应用价值。
Protein-peptide binding plays various important roles in living cells. In many cases, the peptide- binding sites of proteins are not known in prior. Then, computational prediction of the peptide- binding sites is desirable. Popular programs for protein-peptide docking usually depend strongly on the initial positions of peptides, such as Rosetta. To overcome this limitation, here we develop a global docking approach in which the peptide is initially distributed evenly on 26 surface locations of a virtual sphere around the protein, and define a selection parameter for discriminating native-like binding site from non-native sites. We used this approach to predict the native-like binding conformations of peptide-protein complexes, and in most cases the peptide-binding sites were correctly predicted, with Cα-RMSDs below 5.5 ? with respect to the crystal structures of peptides. The results of this study suggested that our approach may be very useful for the identification of peptide-binding sites of proteins.
