【Abstract】 According to the analysis of the high-cut slope of soft rock where is easy to have problems in the Xiaotang-Gantang section of Beijing-Zhuhai Expressway, a reasonable engineering technology of strengthening and protecting the high-cut with soft rock is suggested. The strengthening engineering includes unti-slide piles, prestressed anchoring piles, pile-sheet retaining wall, gravity retaining wall, and the stone retaining wall and the vegetated slope. The construction method of strengthening the slope cut in steps is introduced.更多还原
