1 总 则
1.0.1 为明确泥炭土海砂路基施工技术标准,规范施工要求,保证施工质量,制定本标准。
1.0.2 本标准适用于以海砂为路基填料的新建和改扩建泥炭土地质条件工程等施工,其他类似工程可参考使用。
1.0.3 泥炭土海砂路基工程的施工除应符合本标准的规定外,尚应符合国家、行业、地方现行有关技术标准的规定。
2 术语和符号
2.1 术 语
2.1.1 路基 subgrade
按路线位置和一定技术要求修筑的带状构造物,是路面的基础,承受由路面传来的行车荷载。
2.1.2 路床 roadbed
路面结构层以下 0.8m或 1.Zm范围内的路基部分,分为上路床和下路床两层。上路床厚度 0.3m;下路床厚度在轻、中及重交通时厚度为 0.sm,特重、极重交通公路时厚度为 0.9m。
2.1.3 路堤 embankment
高于原地面的填方路基。路堤在结构上分为上路堤和下路堤,上路堤是指路面底面 以下,在轻、中及重交通时 0.8m一1.sm厚度范围或特重、极重交通公路时 1.Zm~1.gm厚度范围的填方部分;下路堤是指上路堤以下的填方部分。
2.1.4 泥炭土 peat
泥炭土是泥炭质土和泥炭的总称,指有机质含量大于 10%,含水率高、孔隙比大的第四系软弱土。
2.1.5 桩网复合地基
桩网复合地基是由刚性桩、桩帽、加筋层和垫层构成的,适用于处理勃性土、粉土、砂性土、淤泥、淤泥质土、泥炭土等地基的一种复合地基。
2.1.6 海砂 sea sand
出产于海洋和海洋口附近的砂,包括海滩砂、海底砂和入海口附近的砂。
2.1.7 海砂路基 sea sand一filled subgades
用海砂作填料的路基称为海砂路基。
2.1.8 路基横坡 subgade cross slope
路基横断面上路槽中心线与路槽边缘两点高程差与水平距离的比值,以百分率表示。
2.1.9 压实度 degree of compaction
路基压实后的干密度与标准最大干密度之比,以百分率表示。
2.1.10 弯沉 deflection
路基或路面在荷载作用下产生的垂直弹性变形。
