LPG地下洞库工程地质条件浅析

Analysis of Engineering Geologic Conditions for Constructing LPG Underground Storage Caverns

在ＬＰＧ地下洞库的建设中，选区的工程地质条件起决定性作用。围岩稳定条件主要是库区区域稳定性，洞库所属山体的稳定性，以及对建库围岩工程地质条件的分析。水封条件取决于地下水位和采取人工加压措施后能否高于设计水位。

The engineering geologic conditions in the selected area of constructing LPG underground storage caverns played a decisive role.The stable conditions of the surrounding rock were mainly the stability of storage area and that one which storage caverns belonged to the mountain system and the analysis of the engineeringgeologic conditions of surrounding rock for building storage caverns. The water seal conditions depended on the level of underground water and whether the water level was higher than the designed one or not after using the artificial pressuring measures.
