2、同時(shí)對(duì)環(huán)境產(chǎn)生極大破壞,邊坡柔性防護(hù)技術(shù)是工程防護(hù)與植物防護(hù)有機(jī)結(jié)合的新型防護(hù)方法,它充分利用工程防護(hù)深層加固和植物淺層固坡及生態(tài)環(huán)保的特點(diǎn)達(dá)到工程建設(shè)與環(huán)保及生態(tài)恢復(fù)兼顧的目的,現(xiàn)在邊坡柔性防護(hù)技術(shù)已成了高速公路邊坡防護(hù)的一種趨勢(shì),代表著邊坡防護(hù)的發(fā)展方向。本文主要從甘肅地區(qū)黃土公路邊坡病害類型和產(chǎn)生機(jī)理出發(fā),以甘肅省平(涼)~定(西)高速公路黃土高路塹邊坡防護(hù)工程為背景,通過(guò)現(xiàn)場(chǎng)降雨沖刷試驗(yàn)對(duì)比無(wú)防護(hù)、植物纖維護(hù)坡、植被板護(hù)坡這三種方式的防護(hù)效果并結(jié)合土工格室護(hù)坡室內(nèi)降雨沖刷試驗(yàn),研究了降雨沖蝕影響因素及其三種防護(hù)形式對(duì)邊坡穩(wěn)定性的作用程度,探
3、討了植物纖維護(hù)坡、植被板和土工格室這三種柔性防護(hù)方式的加固機(jī)理,提出了相應(yīng)的設(shè)計(jì)方法及施工工藝,通過(guò)有限元數(shù)值分析,說(shuō)明了柔性防護(hù)技術(shù)對(duì)黃土地區(qū)高速公路邊坡治理與防護(hù)的作用,同時(shí)對(duì)柔性防護(hù)方式技術(shù)進(jìn)行了經(jīng)濟(jì)社會(huì)效益的分析,為黃土地區(qū)的公路邊坡病害防治工作提供了理論依據(jù),可為黃土地區(qū)公路邊坡防護(hù)所借鑒。關(guān)鍵詞:黃土,邊坡,柔性防護(hù),降雨沖刷試驗(yàn)AbstractWiththequestionofthesurvivalanddevelopmentofthecontinuousdeepeningofawareness,people’Sawarenessof
