在铁路和公路的挖方地段和在具有陡峭边坡的填方处修建挡墙时,在工费、工期、结构物的机动变形适应性和具有环境保护功能等方面,可能遇到特殊的要求。因此,近10年来,要求鞋常用的重力式挡墙和锚杆挡墙进行设计革新,而钢筋混凝土结构,在实现工费省、工期短、具有可机动变形的造形,对于困难地基条件具有适应性以及具备环境保护功能方面,已处于难以解决的境地。现采用的新型挡墙,实质上可分为两大类:一为力学稳定填筑;一为预制节段拼装架立的重力式挡墙。前一类是指加筋土挡墙,即常用的具有
Construction of retaining walls at excavations of railroads and highways and at fillings with steep slopes may meet special requirements in terms of labor costs, construction schedules, maneuverability and adaptability of structures, and environmental protection functions. Therefore, in the past 10 years, the commonly used gravity retaining wall and anchor retaining wall are required to carry out design innovation. However, the reinforced concrete structure has the advantages of low labor cost, short construction period, maneuverable deformation shape and adaptability to difficult foundation conditions Sex and have the function of environmental protection, has been in a difficult situation. The new retaining wall now in use can be divided into two major categories: one is stably filled with mechanics; one is a gravity retaining wall erected by prefabricated segments. The former refers to the reinforced earth retaining wall, which is commonly used
