基于地基变形控制的采空区地面塌陷地质灾害防治

为有效进行采空区地面塌陷灾害防治,通过运用概率积分法对采空塌陷区地面残余变形进行科学预测,结合建设工程自身对地基变形要求,进行地质灾害危险性定量评价方法研究,并提出针对性防治措施。结果表明:可以有效解决地质灾害危险性评价过于保守和地质灾害过度治理的问题,同时可合理缩短建设工期,大幅降低工程造价,使采空地面塌陷区的土地作为建设用地得到高效利用。经过大量工程实践,地质灾害危险性得到有效控制,工程自身安全和使用功能得到可靠保障,社会经济效益显著。可见该方法切实可行,对采空地面塌陷区的土地利用和工程建设具有借鉴意义。

Study on Prevention and Control of Ground Subsidence GeologicalHazard in Goaf Based on Foundation Deformation Control

The probability integral method is used to predict the residual deformation of the ground in the goaf subsidence area scientifically.combined with the requirement of the foundation deformation of the construction project itself, the geological hazard risk is evaluated quantitatively, and the corresponding prevention and control measures are put forward. The study shows that it can effectively solve the problems of over-conservative risk assessment of geological hazards and over-treatment of geological hazards, and can reasonably shorten the construction period, substantially reduce the project cost, so that the land in the goaf subsidence area can be used as construction land efficiently. Through a large number of Engineering practice, geological hazards have been effectively controlled, the project''s own safety and use function have been reliably guaranteed, and the social and economic benefits are remarkable.The method is practicable and has reference significance for land use and engineering construction in the ground subsidence area of goaf.
