摘　　要：以常见的圆形和直墙拱形洞室为对象 ,借边界元方法模拟计算得出不同条件下地下洞室围岩中位移的分布规律和泊松系数、杨氏模量、初始地应力分布、洞形和尺寸等因素的影响。根据使各测线位移量测相对误差为最小的原则 。Based on common round and arch cavities, and the results from analog computation using Boundary Element method, the following is achieved, such as the laws for displacement distribution of underground cavities from surrounding rocks in different conditions, Poisson's ratio, Young's Modulus, and factors like initial earth stress distribution, form of and size of the cavity, with suggestions optimizing the arrangement of instruments in comparison of traditional methods.
