摘要
文章对山区斜坡桥梁桩基的载荷原理进行了分析,并结合桩基附近地质的弱化特点,提出了山区斜坡桥梁桩基施工稳定性控制模型,通过特定试验结果对比、分析和验证了该模型的正确性与可行性。同时,对桩体的弹性阈量以及嵌固深度等进行了细致的讨论,研究其对山区斜坡桥梁桩基施工过程中的稳定性的影响,研究表明,桩基深度以及弹性阈量对山区斜坡桥梁桩基在施工过程中的稳定性均有较大影响。
This article analyzed the load principle of pile foundation for the bridges in mountain slope, and combined with the weakening characteristics of the geology near the pile foundation, it proposed the stability control model for pile foundation construction of mountain slope bridge, then through the specific test results, it compared, analyzed and verified the correctness and feasibility of this model. Meanwhile, it discussed the elasticity threshold and embedding depth of pile body in details, studied its influence on the stability of pile foundation of mountain slope bridge during the construction,and the results showed that the pile foundation depth and elasticity threshold have great influence on the sta- bility of pile foundation of mountain slope bridge during the construction.
