无缝桥引板微型桩-土共同作用试验研究
Study on micropile under approach slab and soil interaction in jointless bridge
摘要
Abstract
The full scale test of micropile in sand under lateral load is carried out using the hydraulic servo testing system, and the lateral displacement, bending moment of the micropile and the soil-pile reaction at different depths are obtained. The test results show that, the displacement and bending mo-ment of micropile mainly concentrated within the scope where the distance below the top of the pile is about 10 and 15 times diameter of micropile respectively、hyperbolic function of p-y curve is more ac-curate compared with parabola function and hyperbolic tangent function.关键词
