粤东某山区高速公路路堑边坡动态设计应用与实践

Dynamic Design Application and Practice of Highway Cut Slope in a Mountainous Expressway in Eastern Guangdong Province

由于高边坡工程地质的复杂性及施工图设计阶段地质勘察的局限性,施工图设计方案不可避免与现场存在一定的偏差。为及时修正和完善边坡施工图设计,加强现场动态跟踪调查,尽早发现和尽量避免可能产生的地质灾害,确保工程质量及各种工程措施的设计达到经济合理和安全可靠的要求,有必要在路堑边坡施工过程中坚持动态设计理念。以粤东某山区高速公路路堑边坡为例,介绍了该高边坡的地质等情况,根据边坡的实际情况及时开展了动态设计调整,确保了治理方案的合理性,可为类似工程提供参考。

Due to the complication of engineering geology of high slope and the limitation of geological exploration in the construction drawing design stage, the construction drawing design scheme inevitably has certain deviation with the site. For timely correction and improvement of slope construction drawing design, strengthening of the dynamic tracking survey, in order to find as early as possible and try to avoid possible geological disasters, ensure the quality of the project and the design of all kinds of engineering measures to achieve the requirement of the economic and reasonable and safe, it is very necessary to adhere to the concept of dynamic design in the process of cutting slope construction. Taking the highway cutting slope in a mountainous area in eastern Guangdong Province as an example, in this paper, the geological situation of the high slope has been introduced, the dynamic design adjustment in time according to the actual situation of the slope has been carried out, which has ensured the reasonableness of the treatment scheme, and provided reference for similar projects.
