摘　　要：双曲拱坝是近几年来兴起的一项筑坝技术[1]。由于其在竖直和水平两个方向均为曲线[2],常规测量方法难以准确获取体型误差;同时在施工过程中,体型误差作为衡量施工结果的重要依据必须现场得出,对作业人员提出了更高的技术要求。针对这一问题,设计了一套体型误差获取方法,然后将算法移植到安卓平台上,实现体型误差的自动化获取,并将成果应用于三河口水利枢纽大坝体型控制作业。此方案摆脱了常规方法的束缚,计算结果可靠,节省了人力、物力和时间,有效提高了工作效率。Doublecurved arch dam is an emerging dam construction technology in recent years.However,Double curved arch dam is curved in both vertical plane and horizontal plane,so it is difficult to accurately obtain the shape error by conventional measurement methods.At the same time,in the construction process,the shape error as an important basis for measuring the construction results must be obtained on-site,which puts forward higher requirements for the shape control.Based on the design principle of double curved arch dam,we designeda set of shape error cal-culation method for rolling parabolic double curved arch dam.At the same time,taking advantage of the portability of Android smart phones,we developed a set of body shape error calculation tool,which could calculate the body shape error at any time and anywhere through arbitrary obser-vation data.This method can getrid of the shackles of conventional calculator programming and greatly improve the work efficiency.
