【摘要】：近年來隨著我國高速公路建設的快速發(fā)展,國家越來越重視生態(tài)防護的研究,但是由于我國起步較晚,生態(tài)防護研究及植被恢復體系仍遠遠跟不上實際工程的需求。造成了高速公路工程建設的諸多問題,嚴重的制約了我國高速公路建設的快速發(fā)展。為了解決這種困頓的局面,我國加大了生態(tài)防護及植被恢復體系的研究力度。生態(tài)防護及其相關的理論研究成了邊坡防護的新趨勢。眾所周知,強降雨沖刷及入滲經(jīng)常是造成邊坡破壞的主要因素。在本文的研究中,將采用室內模擬試驗的方式,研究面流沖刷入滲對于邊坡影響；首先本文通過查閱大量的文獻了解總結了前人對于邊坡雨水入滲的研究,進而提出了四種新型的生態(tài)防護,即：土工布防護結構、水泥砂漿防護、短管防護結構、草繩防護結構,并詳細介紹了四種防護的結構形式及抗沖刷機理。然后通過采用試驗裝置模擬邊坡,并在邊坡上鋪設四種新型的防護形式,再利用面流裝置沖刷邊坡,按要求取邊坡內土體測含水率,將所得的數(shù)據(jù)進行統(tǒng)計并繪制含水率等勢線,分析研究不同防護形式對于邊坡的影響。最后選取水泥砂漿防護進行野外試驗,通過野外試驗驗證水泥砂漿防護的抗沖刷及入滲的效果,并觀察其對于植被生長的影響,同時對該種防護的施工工藝進行了探索,在結合其他的傳統(tǒng)防護施工工藝的基礎上,研究水泥砂漿防護的施工工藝及細則,為其在以后工程上的應用提出借鑒與參考。
[Abstract]:In recent years, with the rapid development of highway construction in China, the country pays more and more attention to the study of ecological protection. However, because of the late start of our country, the research of ecological protection and vegetation restoration system are still far from keeping up with the demand of actual projects. It has caused many problems in highway engineering construction and seriously restricted the rapid development of highway construction in China. In order to solve this difficult situation, the study of ecological protection and vegetation restoration system has been strengthened. Ecological protection and related theoretical research have become a new trend of slope protection. It is well known that heavy rainfall erosion and infiltration are often the main factors causing slope failure. In the study of this paper, indoor simulation tests will be used to study the impact of surface flow erosion infiltration on slope. Firstly, this paper summarizes the previous research on slope Rain Water infiltration by consulting a large number of documents. Four new types of ecological protection, namely, geotextile protection structure, cement mortar protection, short pipe protection structure and grass rope protection structure, are put forward, and the four types of protection structure and anti-scour mechanism are introduced in detail. Then the slope is simulated by the test device, and four new protection forms are laid on the slope. Then the slope is scoured by the surface flow device, and the soil moisture content is measured according to the requirements. The influence of different protection forms on slope is analyzed and studied by statistics and drawing water content isobaric line. Finally, select cement mortar protection for field test, through field test to verify the effect of cement mortar protection against erosion and infiltration, and observe its effect on vegetation growth, and explore the construction technology of the protection. On the basis of other traditional protective construction techniques, this paper studies the construction technology and detailed rules of cement mortar protection, and puts forward reference and reference for its application in future projects.
