When contemporary raw-soil building is replaced by industry building, the hometown building culture is perishing gradually. In order to inherit and develop the Hanzhong local building, rammed earth wall in Taiyangling and Cangshe hometown is investigated, and the characteristics and construction techniques of the local rammed earth wall are concluded. According to the construction problems, the improvement suggestions are put forward, which establishes the foundation to investigate rammed earth wall further, and guide Rural House construction.展开更多

Two improved suggestions were given after analyzing the results of the investigation. One is to further plan the market of designing of city recreational square, and to manage and maintain the city recreational square; the other is to make good policies to control and avoid some large scale political projects.展开更多
