| 摘 要： | 锚杆静压桩托换技术施工采用分节压桩,整桩压入时压力不连续,区别于中长预制桩的压桩方式。压桩力受地层影响较为明显。特别是粘性土与砂性土中压桩,最终压桩力的大小有明显区别。在无试桩结果条件下,正确采用最终压桩力,是设计部门较为关心的问题,关系到是否满足单桩设计要求的问题。通过实例,依据基桩静荷载测试成果、小应变动测资料,对在砂性土中锚杆静压桩最终压桩力与设计单桩承载力值的关系,进行分析探讨,并在理论上作了粗浅的定性分析,本文在实际应用中,可作为取用或调整Kp值的依据。

| Abstract: | The anchored static pressure pile is different from the long prefabricated pile because the pile pressure is completed by segments and the pressure is discontinuous. The pressured pile is obviously affected by strata, especially, difference of the final pressure is apparent for the clayey and sandy soils. The final pressure of pile is a key problem for designing without the experiment. This paper demonstrates the relationship between the final anchored pressured pile in sandy soil and the designed single pile capacity based on the testing results of static load of basal pile, motion testing data of small strain. This testing result can used as the evidence for Kp value. |
