中衛(wèi)—貴陽(yáng)聯(lián)絡(luò)線BE106滑坡設(shè)計(jì)

摘 要

   本設(shè)計(jì)以中衛(wèi)—貴陽(yáng)聯(lián)絡(luò)線BE106滑坡勘察報(bào)告為依據(jù)，分析了滑坡的工程地質(zhì)條件及基本特征。在此基礎(chǔ)上研究了影響滑坡失穩(wěn)的因素，進(jìn)而分析了滑坡的成因機(jī)制。然后對(duì)滑坡的穩(wěn)定性進(jìn)行了定性評(píng)價(jià)，并采用極限平衡原理和傳遞系數(shù)法，計(jì)算出滑坡的穩(wěn)定性系數(shù)和滑坡推力，對(duì)滑坡穩(wěn)定性進(jìn)行了定量評(píng)價(jià)。按照“經(jīng)濟(jì)合理，工期短，工程技術(shù)可行，治理效果安全可靠”的設(shè)計(jì)原則，從中選取了抗滑樁+排水工程的治理方案，對(duì)滑坡做了治理設(shè)計(jì)。

Abstract

    Based on the geo-technical data of the BE106 landslide, the geological condition about the landslide was studied, then the factors which tampered with the slope’s stability were construed, the reasons which caused the landslide were analyzed and the landslide’s stability was estimated. According to the unbalance thrust transmission coefficient method’s principle and supposition，the landslide’s stability coefficient was calculated. Then the landslide’s stability was appraised. Based on the analysis, the treatment measure were advanced. According to the result of the slope stability calculation, the design principle was that the project cost was reasonable, time limit for the project was much less, the technique was possible and the project was simple and easy to construct. Finally, a revised designing program has been chosen, which included anti-slide pile and drainage works . At last，the slope’s designation of remedying engineering was made.

Keywords: landslide, stability, anti-slide pile, drainage works
