新型支挡结构在重庆山区公路中的应用

针对重庆山区公路地质条件较差、地形复杂、原材料缺乏等特点,根据不同的地质地形条件,提出石笼挡墙、石笼加筋土挡墙、锚杆(基础)挡墙等新型支挡结构,并建立设计计算方法。通过工程应用明确其工作特点,提出施工工艺与质量控制方法,丰富山区公路特殊支挡结构物形式。

Application of New Retaining Structures in Mountainous Expressways of Chongqing

Aiming at the features such as bad geological conditions,complex terrain and lack of raw materials,etc.and in accordance with different geological and topographic conditions,this paper proposes new type retaining structures such as gabion retaining wall,reinforced gabion retaining wall and anchor rod(roadbed) retaining wall,etc.and establishes the design calculation methods.The operating features of new type retaining structures are made clear via the applications in projects and the technology and quality control methods for construction are put forward,thus enriching the forms of retaining structures used in mountainous expressway.
