路基路面工程
总论
路基路面的基本性能:、、、、五、表面抗滑性能。
影响路基路面稳定性的因素:1)地理条件;2)地质条件;3)气候条件;4)水文和水文地质条件;5)土的类别。
我国公路用土依据土的颗粒组成特征,土的塑性指标和土中有机质存在的情况,分为巨粒土、粗粒土、细粒土和特殊土四类,并进一步细分为11种土(见P8)。
我国7个一级自然区:I区——北部多年冻土区;II区——东部温润季冻区;III区——黄土高原干湿过渡区;IV区——东南湿热区;V区——西南潮暖区;VI区——西北干旱区;VII区——青藏高寒区。
路基按其干湿状态不同,分为四类:干燥、中湿、潮湿和过湿。
在公路勘测设计中,确定路基的干湿类型需要在现场进行勘查,对于原有公路,按不利季节

作区。
用于表征土基承载力的参数指标有土基回弹模量、地基反应模量和加州承载比等。
路基的主要病害有:1)路基沉陷;2)边坡滑塌;3)碎落和崩塌;4)路基沿山坡滑动;5)不良地质和水文条件造成的路基破坏。
一般路基设计
路基横断面的典型形式,可归纳为路堤、路堑和填挖结合三种类型。
路基宽度:路基宽度为行车道路面及其两侧路肩宽度之和。
路基高度:路基高度是指路堤的填筑高度和路堑的开挖深度,是路基设计高程和地面高程之差。
路基边坡坡度:公路路基的边坡坡度,可用边坡高度H与边坡宽度b之比值表示,并取H=1.
压实度是填土工程的质量控制指标,土的压实度等于土的控制干密度与最大干密度的比值。

:
砂类土路基边坡渗水性强、黏性差,边坡稳定主要靠其内摩擦力支承,失稳土体的滑动面近似直线形态。其分析方法包括:试算法和解析法。
:
一般来说土均具有一定的黏结力,因此边坡滑动面多数呈现曲面,通常假定为圆弧滑动面。圆弧滑动面的边坡稳定计算方法有:一、圆弧滑动面的条分法;二、条分法的表解和图解;三、圆弧滑动面的解析法。
第五章路基防护与加固
(种草、铺草皮、植树等)和工程防护(抹面、喷浆、勾缝、石砌护面等)。植物防护以土质边坡为主,工程防护以石质路堑边坡为主。
:
抹面防护适于石质挖方坡面,岩石表面易受风化,但比较完整,尚未剥落,如页岩、泥砂岩、千枚岩的新坡面。
喷浆施工简便,效果较好,适用于易风化而坡面不平整的岩石挖方边坡,厚度一般为5——
