局部加强
局部增强

The principal conclusions include : ( a ) the composite system is composed of both active - bearing structural members and inactive - bearing ones , being of a character of combination of rigid retaining structures with flexible ones , so its working mechanism will be behaved as sharing loadings , waterproof and impermeability , loading transfer , local reinforcement and pre - reinforcement ; ( b ) the experimental results show that much more subsoil will participate in retaining action , soil stresses of internal slope will be shared uniformly and deflections caused by excavation will be reduced notably because of cooperation of nails and cement - soil mixing pile wall ; and ( c ) the internal forces of facing in vertical model will be a control factor of design and the cross section tensile strength of cement - soil wall will govern strength of the
主要研究结论有： ( 1 )复合土钉支护的作用机理主要为临时加固土体以保证局部稳定、有机联系以共同承担荷载、改善土体性质起到止水抗渗作用。 ( 2 )试验结果表明：复合土钉支护能够充分调动周围土体共同作用，有效地控制基坑变形；复合土钉支护中止水帷幕的插入深度和强度对控制边坡变形与失稳有较大作用；复合土钉支护效果明显优于一般的土钉支护。 ( 3 )面层与边坡土体共同变形，设计时可按外力作用下的弹性地基梁进行计算。
