【正文】 the original layer of the natural balance, and exposed to a natural environment, longterm affected by various natural factors, the physical and mechanical properties of rock mass will been great changes, cause rock mass deformation mobile, destroy the stability of the slope, and even cause a series of geological environment problems and the ecological environment problems, such as collapse landslides of soil erosion and damage to vegetation, etc .So to ensure the stability of roadbed and prevention and control of all kinds of roadbed disease, in addition to the drainage roadbed, still need to be bined with the local hydrological geology and material of case, take effective measures to all kinds of soil ShiBianPo necessary protection. Firstly,a slope failure forms and reasons Embankment slope of the slump is one of the most mon roadbed disease, according to slope soil category damage reason and scale is different, the main failure form of slip party peel and broken down landslide collapse four slip party is due to a small soil slope moves down along the soil formed, namely the slope of thin surface soil slip under, it is often due to rainfall precipitation and flowing water erosion caused by improper slope or construction of the landslide is refers to the part of the gravity of soil slope under one of the sliding surface sliding, mainly because of the soil slope of embankment caused by inadequate stability of landslide is the main reason of the side slope steep or spend change clearly feet are hollow, or filling levels arrangement inappropriate, etc.。噴射混凝土法分為素噴法和錨噴法。上述兩種方法在植草初期 ,應(yīng)免受風(fēng)雨的侵蝕 ,可覆蓋纖維網(wǎng) ,由于坡面沒(méi)有任何的加筋處理 ,在暴雨和徑流的沖蝕下極易導(dǎo)致坡面破壞 ,因此一般應(yīng)在每年 35 月進(jìn)行。因此為保證路基的穩(wěn)定和防治各種路基病害 ,除做好路基排水工作外 ,還需結(jié)合當(dāng)?shù)厮摹⒌刭|(zhì)及材料等情況 ,采取有效措施 ,對(duì)各類土、石邊坡進(jìn)行必要的防護(hù)。因此 ,邊坡設(shè)計(jì)應(yīng)遵循“安全綠色、水土保持、恢復(fù)自然、環(huán)保之路”的設(shè)計(jì)原則。漿砌片石護(hù)坡優(yōu)點(diǎn)是耐久性較好 ,適宜防護(hù)不同控制邊坡中的巖土層和不同位置的邊坡 ,且造價(jià)適中 ,故適用于上下邊坡中的一般坡面。 Cut slope is the main reason of the landslide slope height and slope and natural geotechnical levels of nature does not adapt spalling and broken down is refers to the slope rock weathering surface. In different kinds of external environment under the influence of the top rock slope and peeling off from the destroy form of collapse usually refers to the larger stones out along the slope surface slope and tumble down. second ， Embankment slope protection design principles Highway slope distribution along the road of the range, the destruction of the environment of natural range, if in the protection, and can also pay attention to protect the environment and create the environment, the adoption of appropriate green p
