摘要:
在考虑土体抗剪强度参数变异性及相关性的基础上,运用可靠度理论分析洞顶松散土体的塌方概率.根据简化模型推导土体发生某种破坏时的安全余量,计算土体发生塌方的概率值.分析土体抗剪强度参数的变异性及相关性、初期支护对土体塌方概率的影响,有利于对土体的认识和评价,对可能采取的加固措施提供科学依据.工程实例的计算结果表明,可以通过增减初期支护的作用来调整塌方概率.
Abstract:
Considering the parameters variability and correlation between shear strength parameters of soil, the collapse Reliability of soil at the top of tunnel was analyzed by the theory of reliability. According to the simplified model, the safety margin of soil was deduced, and the collapse Reliability of soil was calculated. It is beneficial to understand and evaluate the soil by analyzing the parameters’ variability, correlation of shear strength of soil and the influence of initial support to soil collapse, which can provide scientific basis to consolidate support measures. According to the calculated result of actual engineering, increasing or decreasing the function of initial support can be used to adjust the probability of collapse.
