| 1. | Battered pile and pile group are generally used in bridge , wharf and foundation of transmission power 斜桩以及有斜桩群桩广泛应用于桥梁、码头以及大型输电线路基础等。 |
| 2. | As the limitation of equipment and technology of construction , some vertical piles are constructed to battered piles 同时,由于施工机具、施工技术的限制,地质条件的变化,有的直桩也因施工原因成为斜桩。 |
| 3. | The model is called " generalized elastic theory " in this paper , which can take the plastic behavior of the soil around the pile into account , and also can analyze the battered pile and pile group 这种方法可以考虑桩周土的塑性和桩-桩相互作用,还可以分析斜桩以及有斜桩的群桩。把广义弹性理论法用于单桩分析,建立了相应的模型和公式。 |
| 4. | Then the author gives the method to determine the parameters of the generalized elastic theory . computing examples show that the bearing capacity of the piles depend on the load inclination and the pile battered angle . under the vertical load , the vertical pile has bigger bearing capacity than the battered pile 算例表明,竖向受荷直桩比斜桩有更大承载力;水平受荷单桩, “正斜”斜桩有较大的承载力, “负斜”斜桩承载力较小,直桩居中。 |
| 5. | Under the vertical load , the vertical pile group has bigger bearing capacity than the battered pile group . under lateral load , the positive battered pile group has bigger bearing capacity than the vertical and negative battered pile group . both model experiments and prototype experiments are conducted 与单桩类似,竖向受荷直桩群桩承载力比斜桩群桩大;水平受荷群桩, “正斜”单桩组成的群桩比直桩群桩和“负斜”单桩组成的群桩的承载力大。 |
| 6. | Under the lateral load , the positive battered pile has bigger bearing capacity than the vertical and the negative pile . the allowable settlement of the pile head is suggested and the vertical pile can bear load with inclination of less than 10 , and the battered pile bearing vertical load can be angle of less than 10 . then the paper employed the generalized elastic theory in pile group , considering the interaction between pile - soil 就桩顶的竖向沉降而言,桩身的微小偏斜(小于10 ) ,对竖向受荷桩的正常使用没有明显的影响;倾角太大的斜桩承受竖向荷载的能力有所减少;直桩可以承受一定倾角(小于10 )的倾斜荷载,这时的倾斜荷载对桩顶的沉降影响较小,但桩顶水平位移增加比较明显。 |
| 7. | First , the generalized elastic theory is employed into in single pile analysis . the degeneration solution is accordant with poulos " results . analyzing the load - displacement behavior of the battered pile , the results agree well with meyerhof ' s model experiments and zhanglm ' s centrifuge experiments 对于直桩,退化为弹性理论的计算结果同poulos的结果一致,退化为荷载传递法与他人的结果基本吻合;然后研究了斜桩的荷载-变形特性,把公式用于计算meyerhof的模型试验以及zhanglm的离心机试验的荷载-位移关系,发现同试验结果吻合较好。 |
