重庆南干线整改工程綦江穿越勘察技术

Surveying Technique of Qijiang Traversing of East Section's Improvement Project of South Trunk

重庆南干线东段安全隐患整改工程綦江穿越重要性等级为一级,查明穿越断面的地层结构、松散地层结构的颗粒组成及其工程地质特性,取得合理岩土参数,对整改工程建设具有重要作用。在地质测绘基础上布置勘探点,开展了原位测试、河流表流速测试并取岩芯样及水样进行室内试验。经施工验证,地质勘察成果与实际地质条件基本吻合。

The grade of Qijiang Traversing of east section s potential risk improvement project of south trunk in Chongqing is class I. It is important for the improvement project that to obtain the stratum structure of traversing cross-section,the particle component of loose stratum structure and its properties of engineering geology,then the reasonable geotechnical parameters. The exploration spots is set on the basis of geology surveying,and there are some tests on these spots such as the in-situ test and the test ...
