摘要
软土地基深基坑开挖是岩土工程领域重点研究内容之一。以宁波某深基坑工程为例,针对工程难点,从坑壁土体变形控制、坑底隆起控制和土方运输3方面进行施工方法研究,并对效果进行分析。结果表明,工程施工方法对基坑周边土体的水平位移和地表沉降及基坑底板的隆起进行了有效的控制,基坑施工未对周围建筑物和地下管线产生不利影响。
Technology of deep foundation excavation in soft soil is the one of the key research contents in project fields. Taking a deep foundation excavation project in Ningbo as an example,in view of the engineering difficulties,construction methods are researched from three aspects about the wall of foundation soil deformation control、foundation bottom elevation control and earthwork transportation, and the effect is analyzed. The results show that construction methods can effectively control the horizontal displacement, the ground surface settlement and foundation pit bottom uplift, the foundation excavation has no adverse effect on the surrounding buildings and underground pipelines.
