摘要
为解决传统公路路基填筑施工技术质量与效率较低,无法提高破损路基结构稳定性与承载能力的问题。在传统填筑施工技术的基础上作出了改进,以X高速公路工程为例,深入开展了路基填筑施工技术方案的研究。通过选取路基填石料与施工机具、分布填筑法设计公路路基横断面、在路基中填筑土工合成材料,设计了一种全新的路基填筑施工技术。实例分析证明,新的技术能够提高路基岩性强度,降低路基沉降量与沉降速率,可行性较高。
In order to solve the problem that the quality and efficiency of traditional highway subgrade filling construction technology are low, and the stability and bearing capacity of damaged subgrade structure cannot be improved. On the basis of the traditional filling construction technology, the improvement is made.Taking the X expressway project as an example, the research on the subgrade filling construction technology scheme is carried out in depth. A new construction technology for subgrade filling is designed by selecting subgrade filling materials and construction machines, designing the cross section of highway subgrade with distributed filling method, and filling geosynthetics in the subgrade. The case analysis shows that the new technology can improve the strength of subgrade bed rock and reduce the settlement amount and rate of subgrade,which is feasible.
