摘　　要：介绍了深厚表土层竖井井壁破裂机理的研究现状,指出底部含水层疏水沉降是导致井壁破裂的主因,并通过理论分析和数值模拟,研究了双卸压槽法修复破裂井壁的机理。并将研究成果应用于山东某矿副井井壁的修复工程,实践表明效果良好,为井壁破裂治理提供了参考依据。The research status of wall break mechanism of vertical shaft having deep overburden is explained. It is pointed out that dewatering of water- bearing strata at bottom of shaft is main reason for shaft wall break. The mechanism of repairing broken wall of shaft using Double Pressure-release Troughs Method is studied through theoretical analysis ＆ data simulation. The results of study are applied to repair engineering of broken wall of a auxiliary shaft in Shandong province, achieving good performance. The successful practice provides reference basis for similar cases of broken wall repair.
