摘　　要：根据富水砂层松散地层的特殊性质将冻结井筒分为浅埋和深埋2种情况,分别采用岩柱法和普氏理论对井筒围岩压力进行分析,给出了井筒浅埋和深埋2种情况下富水砂层斜井冻结壁厚度计算方法,现场实践表明富水砂层冻结斜井冻结壁厚度设计方法是合理可行的。Based on the special properties of Water-rich sand stratum ,divided shaft into two cases： shallow and deep, and used rock pillar method and M. M. Promojiyfakonov theory designed the thickness of freezing wall. The practical engineering shows that the design of frozen shaft wall of freezing inclined shaft crossing water-rich sand stratum is reasonable and feasible.
