在淤泥类软土上进行各种施工时,必须对其稳定性作出合理评价。本文以深圳机场堆载预压试验区现场观测资料为基础,分别采用三种不同的方法即孔隙水压力法,有效应力路经法,侧向位移法对填工施工过程中,淤泥土地基的稳定性进行了评价,同时结合实际情况对三种方法进行了综合分析。所得结论对于施工程序的设计有着重要指导意义。 When performing various constructions on soft clay soils, a reasonable evaluation of its stability must be made. In this paper, based on the field observation data of the Shenzhen Airport preloading pre-compression test area, three different methods are used, namely the pore water pressure method, the effective stress path method, and the lateral displacement method for the filling construction process. The stability was evaluated, and the three methods were comprehensively analyzed in combination with the actual situation. The conclusions obtained have important guiding significance for the design of construction procedures.
