淮南某电厂采空区地基稳定性评价及治理方法探讨

Evaluation of Stability of Building Foundation over Goafs & Its Harnessing Method at Power Plant

随着经济和工程技术的发展,人们在采空区上方进行大规模工程建设日益增多。采空区对建筑物安全性的影响就成为关键问题。本文通过淮南某电厂具体实例,对采空区地基稳定性分析评价和治理方法进行了探讨。基于对采空区现状的充分探查,确定了采空区影响边界、垮落断裂带高度及地面荷载的影响深度,预测了采空区二次沉降变形。并根据"分区治理"的原则,为采空区治理提出可靠的依据和有益的建议。

With the development of economy and technology, more and more buildings are constructed over goat＇s. The key problem of such construction is the security of building. This paper evaluates the stability of building foundation over goafs and discusses the harnessing method taking the Huainan power plant as an example. Based on investigation of current situation in goafs, this paper ascertains the influence scope of goafs, height of caving - frac- tured zone and effective depth of ground load effect. And it forecasts secondary settlement deformation of goats. According to the district control principle, this paper puts forward reliable basis and useful suggestion for goafs treatment.
