摘要
主要介绍了利用 Monte-Carlo 随机模拟方法确定北盘江大桥桥基岩体的结构性质。岩体的结构性质是控制岩体物理力学性质进而影响岩体稳定性的最关键的因素,对它的研究历来是岩体力学研究的重点。但由于结构面深埋岩体内部,无法直接观测,因而研究起来特别困难。而 Monte-Carlo 随机模拟方法可根据结构面发育的随机性,并通过对岩体表面结构面的测量,可以很方便地确定岩体结构面三维网络结构,从而揭示岩体的结构性质。从 Monte-Carlo 随机模拟方法在北盘江大桥桥基岩体中的应用可以看出,这种方法十分有效。
It is mainly introduced to use Monte-Carlo stochastic simulation method to evaluate the rock structural characteristics of Beipanjiang Bridge foundation.Rock structural characteristics are the key factors to control the physical-mechanical characteristics and affect the stability of rock mass.The study on the structural characteristics is always the key content of the rock mechanics;and it is very difficult because the discontinuities are usually buried deeply in rock mass and can't be directly observed.Based on the randomici- ty of the discontinuity's developing and the surveying data of the discontinuity which is on the rock mass's surface,Monte Carlo simula- tion method can be used conveniently to determine the 3-D discontinuities network and disclose the rock mass structural properties. This method is very efficient according to the application to the rock in the Beipanjiang Bridge foundation.
