浙赣铁路江西省境内有一个分宜车站,自1964—1974年既有线路基及两侧发生地表塌陷达70余处,危及行车安全,南昌铁路局于1966年、1974年相继进行了工程地质调查与勘探,1974年和1979年我院在南昌局的基础上又作了补充调查与勘探。现将本地区的地形、地貌、地层、构造、水文地质条件、岩溶发育特征、地表塌陷规律等概述如下。
Zhejiang-Jiangxi Railway There is a sub-station in Jiangxi Province. Since 1964-1974, more than 70 surface subsidences have occurred on the existing subgrade and on both sides, which threaten traffic safety. Nanchang Railway Administration successively carried out engineering geological surveys in 1966 and 1974 And exploration, 1974 and 1979, our hospital in Nanchang Bureau on the basis of a supplementary investigation and exploration. The topography, geomorphology, stratigraphy, structure, hydrogeological conditions, karst development characteristics and surface collapse laws of the area are summarized as follows.
