摘　　要：文章结合实际工程案例,探讨了高速公路拓宽路基综合防排水方案设计。研究结果表明,合理地应用综合防排水技术可显著提高路基的稳定性和耐久性,确保道路安全畅通,通过采取文章提出的联合使用碎石排水和排水渠的方案,优化后路基含水量均值下降幅度约为20.15%,验证了该方法在路基排水方面的改善效果,可为高速公路拓宽改扩建工程提供技术支持,并为我国高速公路建设及运营管理提供有益参考。Combined with practical engineering case,this paper discusses the design of comprehensive waterproofing and drainage scheme for expressway widening subgrade.The results show that the reasonable application of comprehensive waterproofing and drainage technology can significantly improve the stability and durability of the subgrade and ensure the safety and smoothness of the road.By adopting the scheme of combining gravel drainage and drainage canal proposed in this paper,the average water content of the subgrade decreases by about 20.15%after optimization,which verifies the improvement eff ect of this method in subgrade drainage.It can provide technical support for expressway widening and expansion engineering,and provide useful reference for expressway construction and operation management in China.
