赤平解析法软件开发及其在水封油库中的应用

Software Development Based on Stereo-Analytical Method for Block Theory and Its Application in Water-tight Oil Storage

摘要:

该文阐明了块体理论赤平解析法可动块体辨识软件Block1.0的理论基础及编制思路，通过赤平解析法和Block1.0就某实例计算结果的对比，验证了Block1.0的准确性；同时，在对锦州地下油库勘察资料进行详细研究的基础上，分别采用Block1.0和Unwedge软件，找出了锦州地下水封储油洞库各开挖面上可动块体的分布情况，从开挖面位置和结构面分布两方面对锦州地下水封油库的稳定性进行系统评价。两者计算结果表明Block1.0更贴近工程实际，可为设计合理开挖方案和有效加固方案的选择提供更为可靠的依据。

Abstract:

This paper presents the theory basis and programming outline of software Block1.0 employed to determine removable blocks based on the stereo-analytical method for block theory, and the result of the software has proved reliable and efficient by comparing with that of stereo-analytical method . In addition, after detailed investigation and study on geologic conditions of JinZhou water-tight oil storage cavern, by using Block1.0 and Unwedge software, respectively, we find all removable blocks relating to each excavation plane of JinZhou water-tight oil storage cavern and systematically calculate the magnitude of removeable blocks with respect to the distribution of discontinuities and the position of excavation planes. The results show that Block1.0 can provide a more reliable basis for the smart reinforcement design of the cavern and be more adaptive to practicality.
