静压PHC管桩施工中,在饱和软土中产生挤土效应,对桩周土体和周围环境造成不良影响,严重时能造成邻近建筑物表面开裂和结构破坏、道路隆起、地下管线断裂等工程事故,通过工程实践,提出采取综合措施,确保工程质量及周围环境得到有效控制。 During the construction of the static pressure PHC pipe pile, the squeezing effect is produced in the saturated soft soil, which has an adverse effect on the soil around the pile and the surrounding environment. In severe cases, it can cause surface cracking and structural damage of adjacent buildings, road bumps and fracture of underground pipelines Through engineering practice, we propose to take comprehensive measures to ensure the quality of the project and the surrounding environment to be effectively controlled.
