摘要
淤泥质土物理性质特殊,在大面积基坑土方开挖施工中有着较大的难度。施工中应分析工程现场地质条件,安排合理的降水方式,在地下水位降低之前尽量减少对土体的振动和扰动,规划好合理的边坡比及边坡支护方式,做好防治措施,才能降低施工难度,节约工程成本。
Muddy soil has special physical properties. It is more difficult to implement earthwork excavation construction of large area foundation pit, Engineering site geological conditions should be analyzed in construction. Reasonable precipitation method is arranged. Vibration and disturbance on land should be minimized before reduction of underground water level. Reasonable slope ratio and slope supporting mode are planned. Prevention and control measures are implemented well, so that construction difficulty can be decreased and project cost can be saved,
