摘要
考虑抗滑桩桩间土拱效应,以桩侧与边坡土体间的摩阻力及黏着力承担滑坡推力的静力平衡条件和土拱跨中与拱脚处截面的强度条件共同控制,建立了抗滑桩间距的计算公式.该公式适当考虑了滑坡推力分布的影响.工程实例表明,该抗滑桩间距计算公式的计算结果较为合理,具有一定的工程应用价值.
In consideration of the soil arch effect between anti-slide piles, a calculation formula for the anti-slide pile spacing was developed, taking the following factors as the controlling conditions-the static equilibrium equation of the frictional resistance and adhesive force between the side of piles and slope soil, which sustains the thrusting force of the landside, and the strength conditions at the medial cross-section and two end sections of soil arch. In the formula, the effect of thrusting force distribution was taken into account. Case study shows that the calculation result of the present method is reasonable, and the method is of certain value for engineering application.
