中山市区的地质构造与岩土工程特性分析

Zhongshan City's Geological Structure and Characteristics of Geotechnical Engineering

通过对中山市区的地形地貌、地质构造、岩土工程特征、水文地质条件等资料的详细分析,总结出中山市区的地形地貌总体南高北低,主要以海拔小于10m的平原为主,部分区域为海拔大于10m的丘陵;市区内的构造断裂较多但活动性不明显,相对稳定;地层结构表现为淤泥层和砂层等软土层较厚,岩层埋深较深,且起伏较大;地下水位较浅却具流动性等特点;通过分析将中山市区的区域地质进一步划分为丘陵山地薄覆盖层区(A)、平原谷地厚软土层区(B)和平原谷地薄软土层区(C),分别对三个区域的岩土工程性质进行描述,为工程建设提供参考。

By analysizing detailedly topography and geomorphology,geological structure, characteristics of geotechnical engineering, hydrogeological conditions of Zhongshan urban , geomorphologlcal of Zhongshan city is south high and north low overall, mainly in the plain of the main elevation of less than 10m, some areas more than 10m above sea level the hill. Tectonic fracture of Zhongshan city more but no significant activity relatively stable. Formation structure performance is silt and sand, thick soft soil,deep depth strata, variation in ups and downs. With the characteristics of shallow groundwater but flow. By analysis regional Geology of Zhongshan urban , further divided into hilly areas of thin overburden（A）,plain valley thick soft soil zone（B）, valley plain area of thin soft layers（C）, separately describing the nature of the geotechnical of three regions, providing a reference for the engineering construction.
