边坡安全系数计算及稳定性分析方法
|
摘要
本文主要研究边坡稳定的初步预测问题,利用MATLAB软件完成以下工作:(1)考虑影响边坡稳定的6个内在因素参数,采用多元二项式回归中的完全二次法进行拟合,并对该拟合的多项式进行验算,验算结果表明:在实际工程中,可以根据边坡的土体力学参数快速直接计算边坡的安全系数。(2)理论上,边坡安全时,边坡安全系数大于1;边坡破坏时,边坡安全系数小于1。针对与理论相反的实际工程情况,运用可拓学原理、层次分析法建立边坡稳定性评价指标体系,提出边坡稳定综合权重判断法:当权值总和>0,安全系数>1,综合指标>1.5时,边坡处于稳定状态。该计算方法具有较广泛的适用性,可为类似问题提供借鉴。
This paper mainly studies the slope stability of preliminary forecast problems, using MATLAB software to complete the following work:(1) considering the six internal factors that affect slope stability parameters, adopt completely secondary method of multivariate binomial regression fitting, and the fitting polynomial calculation, calculation results show that in the practical engineering, can according to the mechanical parameters of the soil of rapid calculation of the slope safety factor directly.(2)For slope safety factor greater than 1, slope failure; when the slope safety coefficient is less than 1 and the slope is stable, the ethnics principle and analytic hierarchy process are used to establish the slope stability evaluation index system, and the comprehensive weight judgment method for slope stability is proposed: when the weight sum is more than 0, the safety coefficient is more than 1, and the comprehensive index is more than 1.5, the slope is in a stable state. This method has wide applicability and can be used for reference for similar problems.
