天柱地区岩土工程地质特征及地面塌陷成因浅析

Geological Feature of the Geotechnical Engineering and Genesis of Ground Collapse in the Tianzhu Area

天柱某在建工地发生的地面塌陷,本文根据本工程建设及其塌陷和同地区大量工程勘察资料,分析阐述了天柱地区的岩土工程地质特征,对塌陷成因进行了初步分析。这对在厚覆盖的岩溶地区进行工程建设尤其是岩土工程勘察具有重要意义。

A ground collapse emerged on a certain building site at Tianzhu County in the year of 2002 which constitute the hazard for engineering and was concerned by relative departments. According to a bulk of this engineering operation and its collapse and survey data of engineering in the same area, the geological characteristic of geotechnical engineering in the Tianzhu area is depicted, the subsided origin is initially researched. That is significant for thickly-overlaid karst regions to carry out engineering construction, especially geotechnical engineering survey.
