石门河倒虹吸主要工程地质问题分析与评价

Analysis and Evaluation on the Major Engineering Geological Problem of the Inverted Siphon at Shimen River

石门河倒虹吸是南水北调中线工程总干渠穿越石门河的交叉建筑物。从地质条件、岩性分布特征等方面,对该工程存在的主要工程地质问题进行分析与评价。

The inverted siphon at Shimen River is a intersected building which the main channel of the Middle Route of South-to-North Water Transfer Project crossed the Shimen river.In this paper,the major engineering geological problems of this project were analyzed and evaluated from aspects of geological condition,lithological distribution characteristic.
