| 摘 要： | 客运专线铁路建设对路基工后沉降的要求十分严格,以京沪客运专线铁路昆山试验段的测试数据为依据,在分析砂桩处理软基方案合理性的基础上,总结了路基预压沉降测试数据的变化规律,并采用双曲线法进行了地基预压期间的沉降预测,基于预测结果,分别获取了该试验段一般路段与路桥过渡段的堆载预压相关设计参数,推测出满足工后沉降要求时控制预压期地基沉降速率的相关参数。

| Abstract: | The requirement of controlling in post-construction settlement in the construction of passenger dedicated railway is improving, based on test data of Kunshan foundation of JingHu passenger railway, this paper analyzes the rationality of sand piles plan in soft foundation, concludes the regularity of test settlement, predicts the precompression term settlement by hyperbola, it obtains relative designing parameters of normal subgrade and bridge-subgrade transition, and predicts controlling parameters of precompression term velocity that satisfies requirement of post-construction settlement, this could be used as reference for relative engineering design and research |
