厂区路基
road bed in the factory zone
ehangqu lu],厂区路基(road bed in the tactory zone’ 厂(矿)区内铁路轨道或道路路面下的底尾飞兰垦然地面起伏不平时,为使路面平顺,在自然地面低于路基设计标高处需要填筑成路堤,而在自然地面高于路基设计标高处需要开挖成路堑。路基必须具有足够的强度和稳定性,在其本身自重作用下不应发生过大的沉降;在车辆动力作用下不应发生过大的弹性变形或塑性变形。路基边坡应能长期稳定而不滑坍。因此,在必要处应修筑路基排水和防护工程,例如排水沟、护坡、挡土结构等。 路墓设计包括路堤和路堑设计,路基排水和防护工程设计以及特殊地区的路基设计。 路堤设计路堤顶面宽度根据铁路轨道道床底宽或公路路面宽加上两侧路肩宽决定。路堤填料要进行选择。按中国铁路和公路部门规定,粗粒无粘性土,细粒含量小于30%的混合土和砂粘土,粘砂土,砂土和轻重砂粘土等宜作路堤填筑材料;轻重粘土和粉质土一般不宜用作路堤填筑材料。路堤边坡在一般情况下采用1:1.5~1:1.75。当地面横坡陡于l:5时,应将原地面挖成宽度不小于lm的台阶。路堤两侧要修筑排水边沟。在多雨和低洼处的路基两侧要修筑护道。跨沟路堤要在底部修筑排水涵洞。土质路堤顶面要设置路拱,石质路堤顶面不设路拱。 路堑设计主要是确定路堑边坡。路堑边坡分:岩石路堑边坡、碎石土类路堑边坡和粘性土路堑边坡。岩石路堑边坡可按平面破坏、楔体破坏、圆弧形破坏或倾倒破坏等形态用力学方法进行稳定性验算确定。较低的路堑边坡可采用工程类比方法确定.碎石土类路堑边坡可用圆弧法或折线法进行稳定性验算确定。粘性土路堑边坡较高时,用圆弧分析法进行稳定桂验算确定。在均质地层情况下,岩石边坡可采用1:。.1一1:1;碎石土类边坡可采1:0.5一1:1.5;粘性土边坡可采用1:士~1:1.5。 路基排水路基沉陷、翻浆冒泥、冻胀凸起、边坡滑坍等病害多与地面水和地下水活动有关。因此,必须修筑地面和地下排水系统,以确保路基稳定。地面排水系统有:(1)在路肩外侧设置路堑侧沟;(2)在路堑边坡顶部以外设置天沟;(3)在路基需要横向排水的陡坡上设置单级或多级吊沟。地下排水系统一般采用渗水暗沟、渗水隧洞、渗水井和渗水管等。 路墓防护路基挡土结构是路基防护的主要措施。常用的挡土结构类型有:重力式挡墙、薄壁式挡墙(悬壁式和扶壁式)、锚杆挡墙、加筋土挡墙和多层锚锭板挡墙。
