摘要
新奥法施工必须合理确定开挖顺序 ,适时适量支护 ,本文以引黄工程总干线一级泵站主厂房为例 ,主要介绍了开挖设计、工程类比法确定支护参数 ,利用两种有限元法通过各自不同开挖步骤下围岩的位移、应力及屈服域的开展和分布规律的互相对照 ,进行围岩稳定分析和支护参数验证。为庞大地下洞室群中的大跨度、高边墙洞室的设计提供经验。
New Australian Construction Method shall reasonably confirm the procedure of excavation and the timing and the feasible of supporting.The text takes example for the GMPS1 and introduces the design of excavation,the parameters of supporting confirmed by analogy and testified by two finite methods to analyze the stable of surround rock and the distributing law of displacement and stress,development and yielding zone of stress.The design method and points for the big span and high wall of caverns can be as reference for the similar project.
