岩体结构面网络模拟的改进与应用

Improvement and application of network simulation of rock mass discontinuities

随着计算机技术的发展,以统计学为基础的结构面网络模拟技术日益完善,被广泛的应用到工程实践中。但在传统的结构面网络模拟中,随机生成的结构面一直未能很好表现出结构面间距的概率分布模型。针对这一点,对随机结构面中心点的生成方式进行了改进,使随机结构面在模拟区内反应出结构面间距的概率分布模型。改进方法使结构面网络模型具有更强的不均匀性,更符合自然状态中结构面的分布形态。改进方法还可以通过控制随机结构面中心点的分布形式来控制模拟区结构面的分布形态,再结合工程实际可以让结构面网络模型更接近其实际形态。

With the development of computer technology,thediscontinuity network simulation technology which is based on thestatistics has been improved and widely used in engineering practice.However, inthetraditional discontinuity network simulation, the random discontinuitiesare unable to show the probability distribution modelfor their spacing. Aiming at this point, the production methodfor the central point of random discontinuities is improved to make random discontinuities show the probability distribution model for their spacing insimulation zone.The improved method makesthe discontinuitynetwork model show more nonuniformity and the distribution form of discontinuities moreconsistent withits natural form.It also can control the distribution form of discontinuities inthesimulation zone by controlling the distribution patterns of central point oftherandom discontinuity.Based onthe engineering practice, discontinuities network model can be closerto its real form.
