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 Luo Yang Expressway as an example, it is proposed that geological prospecting in karst area should be one of the focuses of the overall design work. In the corridor zone determined by the workable stage, comprehensive geologic prospecting is conducted in advance for key road sections, and thorough and meticulous route selection and comparison are conducted according to the geological survey results. Afterwards, the overall design principles are expounded in combination with the characteristics of the project. The design essentials of the specialties such as the route, subgrade, bridge and tunnel in karst area are emphatically introduced, which are of reference significance to the design of similar expressways.
