西气东输—陕京二线联络线工程岩溶区岩土工程条件分析

针对西气东输—陕京二线联络线工程山东枣庄—济南段岩溶区,采用高密度电法、探地雷达、面波及探井、钻探等多种方法和手段对其进行了系统的野外勘察和分析评价,从岩溶区域分布特征阐述了管道沿线岩溶的基本环境类型,通过对其岩土工程条件的分析评价,提出了管道安全性评价结果及不同岩溶地质灾害管道宜采取的防治措施。

GEOTECHNICAL CONDITION ANALYSIS IN KARST AREA ON THE WEST-EAST GAS AND SHANXI-BEIJING GAS (Ⅱ) LINK PIPELINE PROJECT

The object of this text aims to the karst area along the pipeline between Zaozhuang and Jinan in Shandong Province . This project is the Second Connection Pipeline from Shanxi province to Beijing city , which is one part of the West-East gas pipeline Project. Many methods , such as the HD electrical method、Radar、Surface wave、exploratory pit and drilling ,were used to investigate and analyze the site. From the distribution character of the karst land feature, the basic environmental type of the karst in the area along the pipe direction was expatiated in detail. According to the analysis about the civil engineering condition, the estimation about the pipe's security and the Prevention measures to the geologic hazard in different karst area were hold on to construct the pipe properly.
