中文摘要：介绍了某软土岸坡粉喷桩加固水平抗滑实验实例。该岸坡分别进行了天然基础、单桩基础和四桩基础的抗滑实验。通过传感器量测了水平荷载施加过程中粉喷桩桩身应力分布及其变化。实验结果表明,水平荷载作用下:天然岸坡经过粉喷桩加固后,抗滑能力有明显改善;单桩基础和四桩基础的摩擦角、粘聚力对应相差不大,但桩身应力的发挥模式不同;6.0 m以下的水泥土桩桩身应力随水平荷载变化不明显。

外文摘要：Tests on anti-slide behavior of one soft soil bank improved by deep-mixing-cement pile （DMCP） is introduced. Nature soft soil foundation, single-pile foundation and four-pile foundation tests are conducted respectively. Stress cells are placed in order to measure the distributions of vertical stresses along the DMCP shaft during the filed tests. The tests results show that： anti-slide strength of soft foundation increases greatly after DMCP improvement; （2） single-pile foundation and four-pile foundation provide similar cohesion forces and friction angles, but they have different types of vertical stress growth process; （3） change of horizontal force only makes a little difference to vertical stress of DMCP below 6.0 m depth. The test results may serve as a reference for relative engineering design.
