【摘要】：二郎山1號滑坡位于龍膽溪左岸,滑坡前緣采用了坡腳擋墻防沖刷工程,10 a之后位于龍膽溪凹岸部分坡腳擋墻破壞。針對坡腳擋墻破壞形成的原因,對比分析了目前常用沖刷防護(hù)結(jié)構(gòu)的局限性,提出了采用臺坎式擋墻新組合結(jié)構(gòu)進(jìn)行修復(fù),組合結(jié)構(gòu)主要由擋土墻、墻底抗滑鍵、墻腳臺坎以及耐磨肋組成。介紹了組合結(jié)構(gòu)設(shè)計計算方法,并通過造價分析說明臺坎式擋墻結(jié)構(gòu)與其它防沖刷相比在經(jīng)濟(jì)上具有明顯優(yōu)越性,可為其它同類地質(zhì)災(zāi)害防治提供參考。
[Abstract]:Erlangshan No. 1 landslide is located on the left bank of Gentianxi. The slope foot retaining wall is used in the front edge of the landslide. After 10 years, the slope foot retaining wall is damaged in the concave bank of Gentianxi. In view of the causes of the failure of the slope foot retaining wall, the limitations of the commonly used scour protection structure are compared and analyzed, and the new composite structure of the platform bar retaining wall is put forward. The composite structure is mainly composed of the retaining wall and the anti-slide key at the bottom of the wall. The base of the wall and the wear-resistant rib. The design and calculation method of composite structure is introduced, and the cost analysis shows that the platform bar retaining wall structure has obvious economic superiority compared with other scour prevention and control structures, which can provide reference for other similar geological hazards prevention and control.
