通过某软土地层围护结构调整实例,对围护结构类型进行比选,确立对周边环境影响较小的拉森钢板桩结构形式,并提出拉森钢板桩施工过程中采用单根逐根打入法、桩头振动拔桩法等工艺措施,控制其水平位移,研究表明：拉森钢板桩顶水平位移变形量很小,拔除前变形量仅为2 cm～4 cm,能够满足围护使用要求。
通過某軟土地層圍護結構調整實例,對圍護結構類型進行比選,確立對週邊環境影響較小的拉森鋼闆樁結構形式,併提齣拉森鋼闆樁施工過程中採用單根逐根打入法、樁頭振動拔樁法等工藝措施,控製其水平位移,研究錶明：拉森鋼闆樁頂水平位移變形量很小,拔除前變形量僅為2 cm～4 cm,能夠滿足圍護使用要求。

According to the example of the enclosure structure adjustment of some soft soil stratum,the study compares the enclosure structure types,identifies the Larsen steel plate pile which has little influence on the surrounding environment,and adopts the single and one-by-one striking method and the pile head vibration pile pulling method to control the horizontal displacement,and proves by the research that the horizontal displacement deformation of the Larsen steel plate pile is very small and the deformation before pulling is only 2 cm~4 cm,so it can meet the demand of the enclosure.
