基于相互作用原理的深厚富含水基岩冻结立井井壁设计

Design of freezing shaft lining in deep water-rich surrounding rock based on interaction principle

以基于围岩、井壁、水相互作用原理的包神公式为依据,在综合分析井筒穿过岩层的物理力学性质、涌水量和水压等因素后,确定合理的冻结深度和井壁结构形式。对井壁厚度、竖向分段及井壁支护材料进行合理设计,并与拉卖公式计算结果进行对比,为西部深厚富含水基岩类似地层的冻结立井井壁设计提供参考。

According to the Baoshen Formula, which is based on the interaction principle between surrounding rock, shaft lining and water, firstly, the paper comprehensively analyzed the physical and mechanical properties of surrounding rock, water inflow, water pressure and other factors, determined the reasonable freezing depth and shaft lining structure; then designed the thickness of shaft lining, vertical subsection and supporting materials, and compared with the calculation results of Lamech Formula. The study can provide references for the design of freezing shaft lining in deep water- rich sttrrounding rock.
