【摘要】：對(duì)邊坡進(jìn)行加固以提高其穩(wěn)定性時(shí),采用土工格柵是一種經(jīng)濟(jì)合理的選擇。科學(xué)布置土工格柵加固邊坡,是節(jié)約成本、保障生命安全以及保護(hù)場(chǎng)區(qū)周邊自然環(huán)境的關(guān)鍵。本研究旨在評(píng)估十堰市汽車(chē)城某加筋人工邊坡的穩(wěn)定性。通過(guò)極限平衡分析和基于顯式有限差分法的三維數(shù)值分析方法,預(yù)測(cè)土工格柵人工邊坡的穩(wěn)定性。文中采用了FLAC3D和GEOSLOPE數(shù)值計(jì)算軟件進(jìn)行分析,考慮了四種工況和四種強(qiáng)度折減系數(shù),并計(jì)入了滲流和孔隙水壓的影響。其后,分別采用FLAC3D和GEOSLOPE分析邊坡穩(wěn)定性,并對(duì)兩者數(shù)值計(jì)算結(jié)果進(jìn)行了對(duì)比分析。邊坡穩(wěn)定性分析中考慮了土工格柵的影響,即分析邊坡穩(wěn)定性結(jié)果的同時(shí)考慮到了土工格柵的響應(yīng)考慮到邊坡整體的穩(wěn)定,邊坡在第一類(lèi)工況所描述條件下最安全,該工況中包含了邊坡正常使用情況。采用土工格柵可以顯著增加邊坡安全系數(shù)。但十堰北加筋邊坡由于施工不善,綜合分析確定其邊坡穩(wěn)定性安全系數(shù)為1.09,因此,進(jìn)一步提出了幾種加固方案。論文的研究成果對(duì)同類(lèi)工程有重要的參考價(jià)值。本文包括了文獻(xiàn)綜述,49組圖片,14個(gè)表格,和83篇參考文獻(xiàn)。
[Abstract]:When the slope is strengthened to improve its stability, the use of geogrid is an economical and reasonable choice. The scientific layout of the geogrid to reinforce the slope is the key to saving the cost, ensuring the safety of life and protecting the surrounding natural environment. The purpose of this study is to evaluate the stability of a reinforced artificial slope in the city of Shiyan. The balance analysis and the three-dimensional numerical analysis method based on the explicit finite difference method are used to predict the stability of the geogrid artificial slope. In this paper, the FLAC3D and GEOSLOPE numerical software are used to analyze the four working conditions and four strength reduction factors, and the effects of the seepage and pore water pressure are taken into account. Then, FLAC3D and GEO are used respectively. The stability of the slope is analyzed by SLOPE, and the numerical results are compared and analyzed. The effect of the geogrid is considered in the slope stability analysis, that is to analyze the results of the slope stability and consider the response of the geogrid to consider the stability of the slope as a whole. The slope is the most safe under the conditions described in the first type of working condition. It contains the normal use of the slope. The use of geogrid can significantly increase the safety factor of the slope. However, because of the poor construction of the North reinforced slope in Shiyan, the comprehensive analysis and determination of the safety factor of the slope stability is 1.09. Therefore, several reinforcement schemes have been put forward. This article includes a literature review, 49 sets of pictures, 14 tables, and 83 references.
