摘要
依托某高速铁路双排桩板墙结构工程,通过现场试验研究双排桩板墙桩和桩间板后土压力、桩后湿度分布规律。试验结果表明:桩和桩间板后土压力在浅层深度范围内变化规律同土体湿度一致;桩和桩间板后土压力呈K形分布;双排桩板墙桩和桩间板后土压力之间表现有明显的相关性。
Relying on a high-speed railway double-row pile-sheet wall structure project, through field tests, the soil pressure behind the double-row pile-sheet wall piles and the slab between the piles and the humidity distribution between the piles are researched. The test results show that the variation law of the soil pressure behind the pile and the slab between the piles is consistent with the soil moisture in the shallow depth range. The soil pressure behind the pile and the slab between the piles is distributed in a K-shaped. There is a clear correlation between the earth pressures behind the double-row pile-sheet wall piles and the slab between the piles.
