摘　　要：临海深基坑支护形式面临两个难题,一是选择合适的支护结构,二是动水位对基坑开挖产生的影响。刚性桩与塑性混凝土咬合桩组成的联合支护形式,既能有效地解决支护结构受力问题,又能有效阻截地下水及潮汐动水位落差水压力带来的问题,在临海深基坑支护中具有一定的推广价值。There are two challenges for the deep excavation support in coastal area. （1） the reason- able supporting structure~ （2） dynamic water level on the impact of excavation. The rigid- plastic concrete piles can be used as a supporting form, which can withstand the earth pres- sure and also can intercept groundwater and the associated problem. This supporting form has some value to use in coastal area.
