Abstract在泥石流防治工程中,拦挡坝是应用得比较广泛的一种措施。利用土木建筑中的拱结构形式,结合锚杆技术,引入了无铰拱形拦挡坝的概念。在狭窄河谷中,采用无铰拱形坝既可以改善坝体的工作环境,提高其承载能力,又可以减少材料用量,从而降低造价。针对无铰拱形坝的受力特性,进行了分析,提出了加强坝体、实现无铰的构造措施。; Until now,the dam of blocking sand is a usual measure to prevent and control debris flow.Arch is a
general construction style in Chinese traditional buildings,which has many advan tages,such as better bearing capacity
and lower cost etc.In this paper,the authors put forward a new conception,nam ely,non-hinged arch dam
in virtue of arch construction style in civil engineering and anchor.It should be emphasized,in narrow valleys,
non-hinged arch dam has outstanding qualities,nam ely,this style of dam has better structural system to bear load,
meantime people would decrease the am ount of material and the cost of building.The authors analyzed the capacity
of beating load and put forward some measures to reinforce dam and to realize non-hinged.In architectural mechan.
ics analysis,the authors assumed the central axis of arch dam should be circular arC shape.Th e loads that dam
should bear were calculated with experiential formulas.In the mechanical calculation,the elastic center method
was used,nam ely,when the elastic center of non-hinged arch dam Was made sure,researchers Call utilize the
elastic center of dam to calculate the other three restrains of the supporting end so that calculating a hyperstatic
problem can be changed to calculating a static problem.On the two supporting ends of dam ,the authors designed
prestressed anchors to shape rigid supporting and non-hinged,which shall be pressed into clif at one end while
connected with dam at the other end.Some measures were utilized to reinforce dam .i.e.a series of reinforced
concrete layers should be laid in the dam with a special space and a reinforced net concrete cover should be applied
on the front face of dam ,and etc.
