| 摘 要： | 类SMW法的H型钢支护结构,将搅拌桩和H型钢分离,利用H型钢的抗弯刚度承受土压力,利用水泥土搅拌桩止水和阻挡软土的流变。通过施加预顶力、合理布置支撑、正确的拆撑方案等措施,可以有效减小支护结构的变形;通过采用先引孔再打桩、千斤顶顶升拔桩等措施可以有效减小施工对周围环境的影响。

| Abstract: | The H-Type Steel Supporting Structure of A SMW Method(SMW)applies its flexural rigidity to bear earth pressure,cement-soil mixing piles to seal water and control the flowing deformation of soft soils through separate mixing piles and H-type steel.By applying prestress,rational arrangement of supports and correct removal of supports,etc.of the structure,it can reduce the deformation of supporting structure.Through the utilization of boring holes first and driving piles second,and piles pulling by jack-up rig,etc.,it can effectively reduce the influence of the construc-tion to the adjacent environment. |
