摘要:
结合某深水泊位板桩码头的优化设计,进行了遮帘式板桩结构码头的土工离心模型试验.测试了遮帘桩临海和临陆侧的土压力.试验结果表明,在港池形成前,遮帘桩海、陆侧土压力分布基本相同;港池开挖后,遮帘桩临海侧土压力明显低于陆侧.通过设置遮帘桩可减小前墙所受到的土压力,从而使前墙的墙厚保持在合理范围内.

Abstract:
Geotechnical centrifuge model tests of a sheet pile wharf with barrier piles are carried out for optimum design of a deep water sheet pile wharf.The lateral earth pressures acting on the barrier piles both on seaside and landside are measured in the tests.Test results show that the seaside earth pressure distribution of the barrier piles is similar to the landside before excavation of the harbor pond,while after excavation of the harbor pond,the seaside earth pressure is clearly less than the landside.The thickness of the front wall can be controlled within a rational range by using barrier piles to reduce earth pressure acting on the front wall.
Key words:  front wall,barrier pile,earth pressure,sheet pile wharf,geotechnical centrifuge model test
