一、拱坝水平位移观测的精度要求拱坝在施工到一定高度后,将要蓄水时,才需要开始进行水平位移观测.水压力是拱坝的主要荷载,需要观测蓄水前后拱坝各点的水平位移情况.在蓄水前,拱坝的主要荷载是温度荷载,温度荷载比水压力荷载小,其所引起的拱坝变形位移值也小.若要研究温度荷载的情况,则水平位移观测的精度要按科研要求的精度。若不单独研究温度荷载的情况,只是观测蓄水前后的水平位移情况,则观测精度可与运
First, the accuracy of arch dam horizontal displacement observation requirements Arch dam in the construction to a certain height, will be impoundment, it is necessary to begin horizontal displacement observation .Water pressure is the main load of the dam, the need to observe the arch dam before and after the point The main load of arch dam is temperature load, the temperature load is lower than water pressure load, and the displacement of arch dam caused by it is also small.If we want to study the temperature load, the horizontal displacement The accuracy of the observation required by the accuracy of scientific research. If not separately study the temperature load situation, just observe the horizontal displacement before and after storage, then the observation accuracy can be transported
