山区高速公路设计中土石方对路线方案的影响

The Influence of Earth-Rock on Route Plan in the Design of Mountainous Expressway

山区高速公路设计中,设计人员习惯把特殊桥隧、互通立交、军用设施、断裂滑坡等大规模不良地质作为影响路线方案的控制因素,不把调配后准确的土石方作为路线方案比选的控制因素,只是粗略估算一下,其结果误差往往很大。因此,论文分析了山区高速公路设计中土石方对路线方案的影响、弃土场设置原则以及土石方调配注意事项。路线方案优化时应充分重视土石方因素,综合考虑地质、经济、安全、环保等因素,以获得最优的路线方案。

In the design of mountainous expressway,the designers used to take the special bridge and tunnel,interchange,military facilities and fracture and landslide and other large scale unfavorable geology as the control factors of affecting the route plan,and do not take the accurate earth-rock after deployment as the control factor of route scheme comparison and selection,it is only a rough estimate that the error of the result is often very large.Therefore,the paper analyzes the influence of the earth-rock on the route plan in the design of mountainous expressway,the setting principle of the waste dump and the matters needing attention in the allocation of earth-rock.When optimizing the route plan,we should give full consideration to the factor of earth-rock,and take into consideration the factors of geology,economy,safety,environmental protection and so on,so as to get the best route plan.
