防护措施

Particularly four following respect problems of main research of this thesis : first , excavating and optimizing of the road bed and the slope protect , on the basis of influence factor analysis and the slope design principle by the expressway of mountain area of limestone , we excavate the model of optimizing after putting forward the road bed which is suitable for the expressway of mountain area of limestone , through employ this optimize model , we can reduce the amount of road bed excavate , thus maximum reducing slope excavate destruction to environment and pollute ; according to limestone mountain area expressway characteristic of the cutting slope , we use the law of finite element and rmr of revision carry on stability analyze and appraise to their side slope ; combine the limestone rock body characteristic of mountain area , we have analyzed the corresponding side slope safeguard procedures
论文主要研究了以下四方面问题:第一,路基开挖优化。在分析石灰岩山区环境特征的基础上,探讨了石灰岩山区路线设计的原则与方法;在应用有限元数值分析方法对边坡的开挖稳定性进行分析的基础上,提出了陡开挖强支护的石灰岩山区高速公路的路基开挖方式,并建立了填挖平衡,开挖面积最小的石灰岩山区高速公路的路基开挖量优化模型;结合石灰岩山区岩体特性,探讨分析了相应的边坡防护措施。第二,土石方处理及自然水系调治恢复。
