The Design of Comprehensive Waterproofing and Drainage Scheme for Expressway Widening Subgrade
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 effect 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.
