摘要
通过对安溪县后井矿区地质条件、地面塌陷特征、影响因素、形成条件等进行分析,从力学角度和塌陷的各种作用探讨了地面塌陷形成机理。研究结果表明地面塌陷与岩溶发育程度、地下水、第四纪盖层厚度、地质构造、地下开采活动(石灰岩、煤炭)等因素有关,地面塌陷形成主要是土洞顶板的抗剪力小于致塌力所造成,最后提出防治建议。
This author raises the viewpoint that the main reason for the ground collapse, based on the characteristics and principle of the earth sinking in Jiandou Town, Anxi County, from the stand- point of mechanics, are because of inadequate resistance pressure comparing with the pressure causing the sinking. Of course, limestone cave, water underground, the cap thickness of the Quaternary Period, geographic construction, underground mining, etc, also play an important part. Finally, the author puts forward the related counter＇measures.
