摘要:
路基在施工与使用过程中产生的沉降变形会造成路面裂缝、桥头跳车等工程缺陷．在路基施工中经过长短桩复合地基处理能够同时增加承载力并降低沉降大小．但是，针对长短桩复合地基沉降理论计算的研究较少，难以满足实践要求．对比分析了传统计算方法的优缺点与各自的适用性，并基于长短桩复合地基的应力应变特性通过公式推导将明德林解与布辛奈斯克解相结合用于路基沉降值的理论计算，最后对影响长短桩复合地基的沉降理论计算的因素进行了分析的影响因素，为实际工程中长短桩复合地基沉降计算的精确性提供了理论依据．
Abstract:
The settlement of roadbed during construction and service process will result in pavement cracks, vehicle jump at bridge head and other engineering defects. In the construction of roadbed, the bearing capacity can be increased and the settlement can be reduced by the treatment of long short pile composite foundation. However, research on the theoretical calculation of the settlement of long short pile composite foundation is few, and the calculation method cannot meet the practical requirements. The advantages and disadvantages of traditional calculation methods and their applicability are comparatively analyzed. Based on the stress-strain characteristics of composite foundation with long short piles, Mindlin’s solution and Boussinesq’s solution are combined to calculate the settlement value of subgrade through formula deduction. Finally, the factors affecting the settlement calculation of composite foundation with long short piles are analyzed. The analysis of the influencing factors provides a theoretical basis for the accuracy of settlement calculation of long-short pile composite foundation in practical engineering.
