摘　　要：随着人类活动范围的不断扩大,人类开始大规模的开发地下空间,它在扩大城市容量和改善城市环境方面有着广泛的前景,而且比向上部空间开发更为有效,但也带来了一系列的地质问题.由于地质构造、岩土体性质、施工方法等原因很难以定量的方法来评价地下空间开发对周围地质环境造成的损害,当这种损害达到一定程度时就会形成地质灾害.因此,建立地下结构与围岩之间的相互关系就迫在眉睫.笔者在原有弹性力学和岩体力学的基础上结合协同学中的有关理论对地下空间开挖对周围环境的影响进行了初步的探讨.With the expanding of human activities, man has begun to excavate the artificial underground space on a large scale. This practice opens broad prospect for the enlargement of the city capacity and improvement of environment. But excavating also brings about a series of geological problems. Due to geological environment, rock and soil nature, construction method etc. , it is difficult for us to use a quantitative method to estimate the damage of excavating. The damage will result when it reaches a critical moment. It is urgent for us to establish the relationship between the underground structure and surrounding rockmass. The paper talks about the damage of excavation to surrounding environment on the basis of elastic mechanics and rockmass mechanics in combination with relevant synergetic theories.
