路橋畢業(yè)設(shè)計(jì)外文翻譯--淺析公路路基邊坡防護(hù)-公路隧道(存儲(chǔ)版)

  

【正文】 rt 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。當(dāng)水流速度較大時(shí) (如 45m/s),波浪作用較強(qiáng) ,以及河流可能有流木及其他撞擊物等沖擊作用時(shí) ,宜采用漿砌片石防 護(hù) ,必要時(shí)可與浸水擋墻或護(hù)面墻同時(shí)設(shè)置。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。 二、路基邊坡防護(hù)設(shè)計(jì)原則 公路邊坡沿公路分布的范圍廣 ,對(duì)自然環(huán)境的破壞范圍大 ,如果在防護(hù)的同時(shí) ,能夠注意保護(hù)環(huán)境和創(chuàng)造環(huán)境 ,采用適當(dāng)?shù)木G化防護(hù)方法來(lái)進(jìn)行 ,則會(huì)使公路具有安全、舒適、美觀、與環(huán)境相協(xié)調(diào)等特點(diǎn) ,也將會(huì)產(chǎn)生可觀的 經(jīng)濟(jì) 效益、社會(huì)效益和生態(tài)效益。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?、地質(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)。 一、邊坡破壞形式及原因 路基邊坡的滑塌是最常見(jiàn)的路基病害之一 ,根據(jù)邊坡土質(zhì)類別、破壞原因和規(guī)模不同 ,主要破壞形式為溜方、滑坡、剝落和碎落崩塌四種。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。素噴法為直接將高標(biāo)號(hào)砂漿噴射在大致平整的巖面上 ,使坡面易松散的顆粒得以穩(wěn)固 ,保證行車及行人的安全。 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 protective method, can make highway has safe and fortable and beautiful in harmony with the environment and other characteristics, which will create considerable economic benefit and social benefit of ecological benefit so, slope design should follow the safety of soil and water conservation and restoration of natural green environmental protection of the way the design principles thirdly, embankment slope protection method plant grass protection plant protection in the slope is planted on grass or trees to slow down the slope of flow velocity, the use of plant root consolidation of surface soil slope to reduce erosion, so as to achieve the function of the slope protection plant protection not only can beautification highway environment, adjust the temperature wet slope, consolidation and the stability of the slope play a role, and simple economic. Plant grass protection
