东莞西部水乡沿海地区地下水位高,多为饱和粉细砂及淤泥质软土地基,在软基条件下进行基坑支护开挖施工容易引起路面开裂及沉陷变形,造成较大的社会影响。为有效解决软基管槽基坑支护质量控制问题,结合东莞市污水管网工程的实际情况,对软基管槽基坑支护质量控制问题进行分析论证,提出解决措施,为类似工程提供参考。 Due to the high groundwater level in the coastal areas along the waterfront in the western part of the country, most of them are saturated fine silt and silt soft soil foundation. Excavation and excavation of the foundation pit under soft foundation conditions easily cause cracking and deformation of the pavement and cause great social impact. In order to effectively solve the problem of the quality control of the foundation pit of soft foundation pit and the actual condition of the sewer network in Dongguan city, the quality control problems of the foundation pit of the soft foundation pit are analyzed and argued. The solutions are proposed to provide similar projects reference.
