【摘要】：格賓擋土墻作為一種新型的支擋形式在國(guó)內(nèi)很多行業(yè)逐漸得到應(yīng)用,但在高速公路路塹滑塌邊坡處治中應(yīng)用不多,且關(guān)于格賓擋土墻的適用性、經(jīng)濟(jì)性、穩(wěn)定性及操作性目前還很少有人進(jìn)行系統(tǒng)的研究。本文以廣西靖西至那坡高速公路為依托,首先對(duì)格賓擋土墻研究現(xiàn)狀作了回顧和分析,然后通過對(duì)滑塌邊坡影響因素分析,對(duì)格賓擋土墻的設(shè)計(jì)方案及其他方案進(jìn)行對(duì)比,系統(tǒng)闡述了格賓擋土墻的工作機(jī)理及穩(wěn)定性分析,最后詳細(xì)介紹了格賓擋土墻的施工工藝及質(zhì)量控制。主要研究成果如下:(1)經(jīng)過對(duì)滑塌邊坡的實(shí)際工況進(jìn)行分析,明確了格賓擋土墻實(shí)施的適用條件。(2)將格賓擋土墻和其他類型擋土墻進(jìn)行了技術(shù)經(jīng)濟(jì)分析,證明了格賓擋土墻在穩(wěn)定性、經(jīng)濟(jì)性和生態(tài)環(huán)保方面的優(yōu)勢(shì)所在。(3)通過計(jì)算安全穩(wěn)定性系數(shù),證明了格賓擋土墻和邊坡的穩(wěn)定性滿足要求。(4)詳細(xì)闡述了格賓擋土墻的施工工藝和質(zhì)量檢測(cè),并通過實(shí)體工程效果證明了該防護(hù)形式的優(yōu)越性。(5)通過對(duì)格賓擋土墻的研究,可供相似條件下的公路路塹滑塌邊坡處治方式作為參考。
[Abstract]:As a new type of retaining wall, the Rubin retaining wall has been gradually applied in many industries in China, but it is not widely used in the treatment of highway cutting sloughing slope, and the applicability and economy of the Gobin retaining wall are also discussed. There are few systematic studies on stability and maneuverability. Based on the highway from Jingxi to Napo in Guangxi, this paper reviews and analyzes the present situation of the research on the Gebin retaining wall, and then through the analysis of the influencing factors of the landslide slope, compares the design scheme and other schemes of the Gobin retaining wall. The working mechanism and stability analysis of the Gobin retaining wall are systematically expounded. Finally, the construction technology and quality control of the Gobin retaining wall are introduced in detail. The main research results are as follows: (1) through the analysis of the actual working conditions of the sloughing slope, the suitable conditions for the implementation of the Gobin retaining wall are determined. (2) the technical and economic analysis of the GB retaining wall and other types of retaining wall is carried out. The advantages of Gebin retaining wall in terms of stability, economy and ecological environmental protection are proved. (3) the coefficient of safety and stability is calculated. It is proved that the stability of the Gobin retaining wall and slope meets the requirements. (4) the construction technology and quality inspection of the Gebin retaining wall are described in detail. The advantages of the protection form are proved by the effect of solid engineering. (5) the research on the Gebin retaining wall can be used as a reference for the treatment of highway cutting sloughing slope under similar conditions.
