摘要
结合顾桥矿大断面硐室工程地质实际条件,提出了锚杆锚索共同支护、浇注钢筋混凝土支护、联合支护3种技术方案,运用FLAC3D数值模拟软件对这些支护形式的条件下围岩应力特征进行分析,从而得出联合支护为最佳的支护方式。
The article based on the GUQIAO MINING geological condition of large section cavern, put forward three embody projects: combined bolting with wire mesh, pouring reinforced-concrete and combined support, Then by the numerical analyses software FLAC3D, deeply analyzed of the support effect by three embody projects to the whole structure of surrounding rocks.The lasted one has made better control entry stability.
