摘要
沉井施工不可避免地扰动周围地层,导致地表沉降,从而对周围的建(构)物产生影响。结合实际工程,提出地锚式沉井压入施工方案,并对压沉过程中井壁周边土体水平位移、地表沉降、土体分层沉降、管线沉降等的现场施工监测数据进行分析,探讨地锚式沉井施工对周边环境的影响。结果表明,地锚式沉井施工具有下沉速度快、对周边环境影响较小等特点,可为今后考虑施工因素的沉井结构设计提供依据。
Caisson construction will inevitably disturb the surrounding strata,cause surface settlement and impact the surrounding buildings or structures. Combined with the practical engineering experience,the pressing construction scheme of anchor caisson was put forward. The field construction monitoring data in pressing process were analyzed,including the horizontal displacement of soil around caisson walls,ground surface settlement,soil layered settlement and underground pipeline settlement, to investigate the effects of anchor caisson pressing construction process on the surrounding environment. The results show that the anchor caisson pressing construction has characteristics of rapid speed and little effect on the surrounding environment,which can provide the basis for future caisson structural design with consideration of the construction factors.
