【正文】 筋材埋置的方式相對來說也較為容易，這種種的優(yōu)勢也使得土工合成材料廣泛的應(yīng)用于水利、 海港、 公路、建筑、鐵路、電力、采礦、軍工等工程的各個(gè)領(lǐng)域，成為了建筑工程中必不可少的重要材料。眾所周知，土體本身具有一定的抗壓、抗剪強(qiáng)度，但是無法承受拉力。 通過對 加筋邊坡中內(nèi)筋的埋深這一參數(shù) 進(jìn)行研究， 得出了以下結(jié)論 ： 內(nèi)筋的埋深與邊坡滑動帶的位置息息相關(guān)，故而本文建議設(shè)計(jì)人員在確定內(nèi)筋埋置深度時(shí)應(yīng)根據(jù)試驗(yàn)結(jié)果中給出的滑動帶的位置確定為宜。 本文就加筋邊坡中頂筋和底筋的埋深這兩個(gè)參數(shù) 進(jìn)行分析， 得出了以下結(jié)論 ：從定性的角度而言，頂筋 與底筋的埋深對邊坡承載能力的影響并不明顯。 通過對眾多數(shù)據(jù)的分析比較，本文就埋深間距這一參數(shù)得出了以下結(jié)論 ： 隨著埋深間距的減小，邊坡的承載能力大幅提高。顯然，這樣的設(shè)計(jì) 明顯的缺乏理論的佐證。河 北 工 業(yè) 大 學(xué) 畢 業(yè) 論 文 作 者： 王巖 學(xué) 號： 111429 學(xué) 院： 土木工程 學(xué)院 系 (專業(yè) )： 土木工程 題 目： 包裹式加筋邊坡破壞機(jī)制有限元分析 指導(dǎo)者： 王子寒 講師 (姓 名 ) (專業(yè)技術(shù)職務(wù) ) 評閱者： (姓 名 ) (專業(yè)技術(shù)職務(wù) ) 20xx 年 6 月 8 日 畢業(yè)設(shè)計(jì)（論文）中文摘要 題 目： 包裹式加筋邊坡破壞機(jī)制有限元分析 摘要： 包裹式加筋邊坡通過向土體中添置柔性筋材增強(qiáng)邊坡承載能力，具有造價(jià)低廉、施工簡便、與邊坡綠化緊密結(jié)合的優(yōu)點(diǎn)，近年來在工程中得到了廣泛的應(yīng)用。但是，受到其受到作用力時(shí)的破壞機(jī)制仍不明確的影響，設(shè)計(jì)理論尚不完善，往往都是根據(jù)以往的工程經(jīng)驗(yàn)進(jìn)行設(shè)計(jì)。為了完善加筋邊坡的設(shè)計(jì)理論，本文通過 plaxis 軟件建立有限元模型分別討論了位移加載條件下筋材的間距和埋深對邊坡承載能力的影響，通過對眾多數(shù)據(jù)的篩選分析得到了各種參數(shù)的合理取值范圍，針對工程設(shè)計(jì)意提出了具一定指導(dǎo)義的建議。在設(shè)計(jì)工作中， 筋材的埋深間距不宜小于坡高的五分之一也不宜超過 1m。從定量的角度而言，本文建議頂筋與底筋應(yīng)埋至荷載中心位置為宜。 關(guān)鍵詞： 包裹式 加筋邊坡 有限元 破壞機(jī)制 河北工業(yè)大學(xué) 20xx 屆本科畢業(yè)論文 畢業(yè)設(shè)計(jì)（論文）外文摘要 Title: A Finite Element Analysis of the Failure Mechanism of the Encased Reinforced Slope Abstract The reinforced slope of the wrapped type is reinforced by the soft rib in the soil. The reinforced slope of the wrapped type has the advantages of low cost, simple construction, close bination with the slope greening. The wrapped type reinforced slope has been widely used in engineering in recent years. However, the failure mechanism of the wrapped reinforcement slope is still not clear. The design theory of the wrapped reinforced slope is not perfect. Obviously, such design clearly lacks the evidence of theory. In order to improve the design theory of reinforced slope, in this paper, the influence of the distance between the reinforcement material and the depth of the load on the bearing capacity of the slope is discussed by the finite element model of the PLAXIS software. In this paper, through the screening and analysis of the numerous data, the reasonable range of parameters is obtained, and some suggestions for the engineering design are proposed. Through the analysis and parison of the numerous data, this paper draws the following conclusions of the parameters of the depth distance. From the qualitative point of view, with the decrease of the depth of the buried depth, the bearing capacity of the slope is greatly improved. From the quantitative point of view, the depth of the material is not higher than the 1/5 depth of the slope and should not exceed 1m. Through the analysis and parison of numerous data, this paper draws 河北工業(yè)大學(xué) 20xx 屆本科畢業(yè)論文 the following conclusions of the two parameters of the top depth and the bottom depth of the reinforced slope. From a qualitative point of view, the influence of the depth of the top and bottom ribs on the bearing capacity of the slope is not obvious. From the quantitative point of view, this paper suggests that the top and bottom tendons should be buried to the load center position. Through the analysis and parison of numerous data, this paper draws the following conclusions of the depth of the inner rib of the reinforced slope. Tendons within the depth and slope sliding zone are closely related, therefore this paper suggests to design in determining the internal ribs that buried depth should be determined according to the location of the slip zone.
