| 摘 要： | 论文以沿海地区邵三高速公路K117＋775~＋940段滑坡的整治工程为实例,简要说明了滑坡变形的基本情况,对当前滑坡所处的稳定程度进行分析。据此,提出了两个整治工程方案,并分别对两方案的加固工程实施效果进行边坡安全定量分析,对两方案在经济、技术、交通、安全及环境保护等方面进行分析和比较,以便有针对性地进行加固工程设计。文中对采用的整治方案的优化设计进行了说明,对滑坡裂缝的处理作了较详细的介绍。论文对实施效果作了简要的说明,对治理方案存在的缺陷进行评述。以期通过实施效果评价与后评价反馈设计,进一步补充、完善设计,弥补方案评审阶段的不足,提高治理工程设计质量。由于工程实例处于沿海地区,受台风暴雨影响较为突出,文中对相似地区的水毁灾害防治具有一定的参考价值。

| Abstract: | A certain land slide regulation work of expressway in coastal area was presented as an example, the basic circumstances of land slide and deformation were presented briefly, and the stability of current land slide location was analyzed. Two regulation schemes were presented and their corresponding qualitative analyses of slope safety induced by the implementation effect of consolidation work were carried out. The analysis and comparison were carried out from the views of economy, technique, traffic, safety and environmental protection, so that the design of consolidation work was made pertinently. The refined design of adopted regulation scheme was explained and the treatment of land slide crack was introduced in detail. The implementation effect was explained briefly and the shortage of regulation scheme was also commented. The author hoped that by feedbacks of implementation effect evaluation and post evaluation, the design could be eomplemerrted and improved to make up the deficiency of the scheme formed in comment stage and to improve design quality of the regulation work. Because the work located in littoral where the impact of typhoon rainstorm is remarkable, this paper is of reference value for washout disaster prevention in similar region. |
