摘要
以罗阳高速公路为例,提出将岩溶区地质勘察作为总体设计工作的重点之一。在工可阶段所确定的走廊带里,对重点路段提前进行综合地质勘察,根据地勘成果进行深入细致的路线方案比选。之后,结合项目特点阐述了总体设计原则,并着重介绍了岩溶地区路线、路基、桥梁和隧道等专业的设计要点,对类似高速公路的设计具有借鉴意义。
Taking Luoding-Yangchun Expressway in Guandong Province as an example,a new concept in the overall design is put forward.The geological survey is strengthened on the key aspects of the overall design which determined the final detailed design quality.The key design points of route optimization,karst subgrade,bridge base and tunnel site are emphatically illustrated,which is supposed to be helpful for the design of similar expressways in the karst region.
