去年,公路月刊第7期发表了区永典同志“曲线中桩横断面方向的简便测定法”一文,其中,所采取的方法,均涉及到曲线半径,并须通过一定的计算,还没有达到简捷的理想。在野外工作中横断面测量是由横断面组担任,对前边中线钉桩组所选用的曲线半径,往往是不知道的。但 Last year, No. 7 of the monthly road magazine published Comrade Yongjie Yong’s article “A Convenient Method for Measuring the Cross-section Direction of Curved Piles in Curves”, in which the method adopted involves the radius of the curve and must pass a certain calculation and has not yet reached Simple and ideal. Cross-sectional measurements in the field work are performed by cross-sectional groups, which are often not known for the radius of the curve chosen for the front midline nail pile group. but
