【摘要】：膨脹土邊坡的地質(zhì)災(zāi)害問(wèn)題已經(jīng)成為影響公路工程建設(shè)質(zhì)量和公路車輛通行安全性的關(guān)鍵因素，分析工程所在地膨脹土的特性及公路邊坡的穩(wěn)定性是公路災(zāi)害防治的關(guān)鍵。 本文在結(jié)合理論和試驗(yàn)數(shù)據(jù)下，對(duì)某旅游公路膨脹土的一般特性和路塹邊坡穩(wěn)定性進(jìn)行分析并對(duì)實(shí)際工程對(duì)應(yīng)研究了邊坡災(zāi)害防治方案，具體工作如下： （1）分析討論了不同條件下公路邊坡穩(wěn)定性的各種計(jì)算方式。研究了邊坡失穩(wěn)的原因和種類，粘結(jié)力和內(nèi)摩擦角對(duì)邊坡穩(wěn)定性的影響，對(duì)旅游公路邊坡災(zāi)害防治的指導(dǎo)意義。 （2）應(yīng)用極限平衡研究法，通過(guò)采用計(jì)算機(jī)軟件對(duì)旅游公路不同路段的邊坡土體進(jìn)行穩(wěn)定性分析，并對(duì)軟件分析結(jié)果進(jìn)行了安全系數(shù)的規(guī)律研究。 （3）采用實(shí)驗(yàn)對(duì)比法，，在旅游公路部分路塹的土體進(jìn)行了改性試驗(yàn)研究，試驗(yàn)選用生態(tài)改性劑對(duì)公路路塹邊坡土壤進(jìn)行了改性試驗(yàn)，并對(duì)路塹邊坡土壤與試驗(yàn)后土壤進(jìn)行了對(duì)比分析。 （4）對(duì)一般性的邊坡災(zāi)害防治措施進(jìn)行總結(jié)分析，通過(guò)對(duì)實(shí)際旅游公路邊坡土體的穩(wěn)定分析，確定具體防治設(shè)計(jì)方案，在工程中具有良好的效果，對(duì)我國(guó)旅游公路建設(shè)中的邊坡災(zāi)害防治工作具有一定的實(shí)踐參考價(jià)值。
[Abstract]:The geological hazard of expansive soil slope has become a key factor affecting the quality of highway construction and the safety of highway vehicles. The analysis of the characteristics of expansive soil and the stability of highway slope is the key to the prevention and treatment of highway disasters. Under the combination of theory and experimental data, this paper analyzes the general characteristics of expansive soil and slope stability of a tourist road, and studies the corresponding slope disaster prevention scheme for practical projects. The specific work is as follows: 1) various calculation methods of highway slope stability under different conditions are analyzed and discussed. The causes and types of slope instability, the influence of bond force and internal friction angle on slope stability are studied. It is of guiding significance to the prevention and cure of the slope disaster of tourist highway. 2) the stability analysis of slope soil in different sections of tourist highway is carried out by using the method of limit equilibrium, and the rule of safety coefficient is studied. In this paper, the experimental study was carried out on the soil of the cut of the tourist highway by using the method of experimental contrast, and the ecological modifier was selected to modify the soil of the cutting slope of the highway. The soil of the cutting slope is compared with the soil after the test. 4) summing up and analyzing the general measures of slope disaster prevention and control, through the stability analysis of the actual tourist highway slope soil mass, the concrete prevention and control design scheme is determined, which has good effect in the project. It has certain practical reference value for the slope disaster prevention in the tourism highway construction in our country.
