摘要:

地下水封储油洞库是目前世界上石油战略储备的重要设施,为了保证该类大断面洞库的稳定,需要对洞库岩体质量进行准确评价,以便进行合理的支护设计。以某地下水封储油洞库为工程背景,选取4北洞室3个典型地段作为试验地点,采用现场工程地质勘察、三维摄影测量系统(ShapeMetriX 3D)及地质雷达测试技术相结合的手段,查明各地段围岩的工程地质特征及节理分布情况,应用Q系统分类法对试验地点岩体进行稳定性分级,依据工程类比和相关规范确定试验地段的支护方案,并运用FLAC3D数值模拟及现场监测的方法对支护效果进行检验。结果表明,设计支护方案合理,能够保证围岩的稳定。

Abstract:

The underground watersealed petroleum storage caverns are popularly used in petroleum reserve worldwide. The quality of rock mass should be evaluated accurately so as to guarantee the stability of caverns and rational support design. Taking 3 typical sections of 4 north caverns of a underground watersealed petroleum storage cavern for examples, the geological conditions and the distribution of joint are detected by means of geological investigation, 3D photogrammetric monitoring system (ShapeMetriX 3D) and radar detection. And then the rock masses of the test sections are classified by means of Qsystem classification method. The support scheme is decided according to similar projects and related criteria; and the supporting effect is examined by means of FLAC3D simulation and site monitoring method. The construction results show that the support design is rational and the stability of the rock can be guaranteed.

Key words: underground watersealed petroleum storage cavern, rock mass classification, rock mass discontinuity structure, Qsystem classification method, support
