摘　　要：针对意外事故引起的重力式挡土墙滑移,分别从墙基底泥浆化、被动土压力丧失、主动土压力与泥浆静压力的促滑作用等方面分析了产生滑移的原因。并经旋喷树根桩、防滑灌注桩、锚杆等方案比较作出了加固方法的选择;同时对各种加固方案作了技术经济分析。并进一步通过防滑灌注桩抗剪能力计算,论证其安全与可靠性;同时指出了防滑灌注桩的施工技术要点。The cause of gravity retaining wall slipping by accident is analyzed based on the factors in the slimming of wall foundation ground, the loss of passive earth pressure, the accelerating slimming of active earth pressure and so on. On the other hand, the suitable reinforced method is Selected in comparison with various reinforcement schemes such as injection root pile, nonskid pile, anchor bar and so on. At the same time, cost-effectiveness analysis of various reinforcement schemes is made. Finally, the checking computations of shear strength in the antiskid caisson pile further demonstrate its security and reliability. In addition, the vital construction technology of antiskid caisson pile is pointed out.
