摘要
西汉高速是陕西省"米"字形公路主骨架的重要组成部分,是打通秦岭南北,贯通中国西部的交通大动脉。户县至勉县高速公路穿越秦岭主山脉,山大沟深,地形条件复杂,桥梁隧道很多,工程技术要求高,施工难度极大。通过对西汉高速公路在公路建设中水土保持工作的主要成功经验以及达到的效果的探讨,分析总结了高速公路建设存在的问题和通车后弃渣场治理的难度及其原因,提出了今后高速公路建设值得借鉴的几点建议和防治措施:(1)遵循植被自然演替规律;(2)加强生态恢复理论和技术的研究;(3)搞好水土保持;(4)做好水土保持施工监理工作;(5)发现问题及时处理。
Expressway from Xi′an City to Hanzhong City(Xihan Expressway) is an important part of the national freeway network.As a pivotal part of the spider-net shaped provincial transport framework,it connects the northern and southern mountainous areas of Qinling Mountains.The road serves also as an essential corridor facilitating West China.The Huxian—Mianxian section of the expressway perforated through the major mountains of Qinling,where the complex topography is characterized with tall mountains and deep valleys.As a result,the construction of the section has to follow strict engineering standards with high technical requirements,owing to the excessive needs of bridges and tunnels.This study discussed the approaches applied to conserve soils during the construction,their effects,and the experiences obtained in some successful cases.The existing issues were also analysed and summarized for the construction and the followed mitigation of the spoil disposal areas.Last but not least,some suggestions and preventative measures were made for future expressway construction.
