针对目前水利工程中对土石坝边坡的稳定分析和相机相对落后的现状,现通过对概率统计数据和结构为分析基础,针对土石坝边坡是否稳定的问题进行了深入的研究,其中包括土石坝抵抗剪力强度的数据为基础进行统计研究数据特性,对土石坝边坡的稳定可靠性分析方法,以及设计过程中所应使用的标准值和分项系数等数据取值的问题,进行了分析研究,并且结合了实际的工程施工实力进行了简要的说明的说明。这里还给出采用MonteCarlo方法搜索临界滑裂面并解出最小指标的详细做法,以及如何利用安全数据和可靠的指标两者之间的关系来确定最终结构的方法。
Aiming at the current situation of stability analysis of rockfill dam slope and relative backwardness of camera in current water conservancy project, this paper makes an in-depth study on the stability of rockfill dam slope based on the analysis of probability statistics data and structure, including earth and rock Dam shear strength data as the basis for statistical study of the characteristics of the data, stability and reliability of rockfill dam slope analysis methods, as well as the design process should be used in the standard value and sub-coefficient and other data values of the problem Analysis and research, and combined with the actual construction capacity of a brief description of the instructions. The detailed method of searching the critical slip surface by Monte Carlo method and solving the minimum index and the method of how to use the relationship between the safety data and the reliable index to determine the final structure are also given here.
