文章摘要：穿越于秦嶺南麓漢臺(tái)區(qū)北部中低山區(qū)的316國道沿線地質(zhì)環(huán)境條件復(fù)雜,地質(zhì)災(zāi)害類型多樣。每年汛期地質(zhì)災(zāi)害頻發(fā),數(shù)百至數(shù)萬方的危巖體常將路面掩埋,少則堵塞交通數(shù)小時(shí),多則數(shù)天,過往車輛及行人的財(cái)產(chǎn)受到嚴(yán)重威脅。由于316國道為我國南北運(yùn)輸?shù)闹匾ǖ?社會(huì)影響較大。為此,該文在漢臺(tái)區(qū)1：50 000地質(zhì)災(zāi)害詳細(xì)調(diào)查項(xiàng)目的基礎(chǔ)上,將316國道作為重點(diǎn)地段進(jìn)行專題研究,分析316國道沿線地質(zhì)災(zāi)害的類型、發(fā)育特征、成因,并提出了相應(yīng)的防治對(duì)策。調(diào)查分析認(rèn)為316國道沿線地質(zhì)災(zāi)害類型主要為崩塌、滑坡和泥石流;孕育地質(zhì)災(zāi)害發(fā)育的不穩(wěn)定邊坡坡型、坡向、坡高、寬度和厚度等決定地質(zhì)災(zāi)害的發(fā)育特征;降雨和人類工程活動(dòng)是地質(zhì)災(zāi)害的主要誘發(fā)因素。最后,提出了以監(jiān)測預(yù)警和卸荷減載、鋪設(shè)柔性防護(hù)網(wǎng)、設(shè)置抗滑樁等為主的防治對(duì)策,為漢中市國土資源局漢臺(tái)分局等相關(guān)部門地質(zhì)災(zāi)害的防范提供決策與依據(jù),也為公路沿線地質(zhì)災(zāi)害的防治提供技術(shù)支撐。

Abstr：Hantai section of No.316 National Road is located in middle-low mountain areas of the southern Qinling piedmont,along which there are complex geological conditions and abundant geohazard types.Geohazards occurred frequently during flood seasons every year,so the roads are often buried by unstable rocks which have a volume of hundreds to tens of thousands of cubic meters.As a result,traffics are blocked for several hours and even several days.Also,passing vehicles and pedestrians are under great threat.Due to the fact that No.316 National Road is a major channel of China＇s north-south transport and has an important social influence,types and characteristics of geohazards along Hantai section of No.316 National Road are analyzed and prevention countermeasures are proposed based on geohazard investigation of Hantai District at a scale of 1： 50000.Field investigation reveals that collapse,landslides and debris flows are the main geohazards.Slope shape,aspect,height,width and thickness of slope body etc.are main inherent factors that determine development characteristics of geohazards along the road.And,rainfall and human activity are main external factors that induce geohazards in the study area.At last,prevention countermeasures including monitoring and early warning,load shedding,flexible support networks and antislide piles are proposed,providing decision basis for geohazard prevention of Hanzhong City Land Resources Bureau and other relevant departments,and also providing technical support for prevention of geohazards along highways.
