与地面环境协调的地下工程开挖预警方法研究

An Early-Warning Study on Underground Engineering Excavation Coordinated with Ground Environment

针对地下工程开挖引起地面沉降损害的严重性,提出了“开展与地面环境协调的地下工程开挖”的理念,研究了地下工程开挖建设、地下水开采、地下矿物开采引起地面沉降的预警方法,构建了与地面环境协调的地下工程开挖的GIS可视化决策和设计系统,展望了今后进一步的研究方向,以指导地面沉降控制和损害防护工程的实施,达到地下工程开挖对岩土体、地表和地面建筑物、构筑物的损害最小,确保地下工程开挖与地面环境之间的协调关系达到最优化,从而实现地下工程开挖与地面环境的协调.

The concept of ＂developing the underground engineering excavation coordinated with the ground environment＂ is put forward against the serious land subsidence caused by underground excavations. The early-warning methods are investigated to forecast the land subsidence duo to the subsurface engineering construction, groundwater extraction, underground minerals exploitation. GIS visualization decision-making and design systems are set up. The GIS systems can instruct the surface subsidence controtment and protection engineering construction to minimize the damage of ground building, structure and rock-soil environment and optimize the coordination relationship between ground environment and underground excavation. At last the further researches are presented.
