摘要
本文介绍了FLAC程序的主要特点及其适用范围。结合工程实例 ,用FLAC程序详细研究了地基开洞和开洞地基施工顺序的不同对地下洞室稳定性产生的影响 ,模拟结果表明开洞地基的围岩稳定性优于地基开洞。
This paper introduced the main characters of the program FLAC, and its field of application. Through a project, the effect of construction sequence on the stability of hole in underground was investigated in detail. The results show that concerning the stability of hole in underground, the construction after digging holes has advantages over the digging holes in ground.
