Abstract:

Due to the natural and historical reasons, the soil structure is very different to that of inland area in Tangshan coastal area mainly with multi-layer soil structure and soft clay & sand soil in upper part, which leads to high cost of the single pile type with low efficiency, difficult construction and being easy to cause environmental pollution. According to this situation and considering the formation in this area, a set of construction method of flexible-rigid composite pile with cement rejection pile and pre-stressed concrete pipe pile is designed with construction difficulties and cost reduction, efficiency improvement and realization of energy saving and no mud recharge to be an environmental protection demonstration, which provides the reference for foundation engineering construction in this area.

Key words:compound pile; flexible and rigid composite pile; cement rejection pile; pre-stressed concrete pipe pile; bearing capacity of single pile; coastal area
