摘要
在现代桥梁建设过程中,用常规控制测量的方法进行测量难以保证精度,为满足通视要求,往往还需要大量的砍伐工作,通过GPS定位技术在望东长江公路大桥控制网的建立中应用,提高了精度,减少了工作量,降低了成本,取得了事半功倍的效果。
During up-to-date bridge construction,routine measurement control method is hard to assure the precision,further,to meet the visibility requirement,it always needs tremendous felling.Application of GPS orientation technique in establishment of control network of the Wangdong Yangtze River highway bridge has improved precision,reduced work volume and cost and yielded twice the result with half the effort.
