自从拙作《预应力混凝土斜张桥设计构思》(以下简称“构思”)发表以来,承蒙读者关注,对文中某些问题要我提供更多资料或和我进行讨论,除已另星作答外,再总答如下: 一、激光测量问题 有些读者希望能看到更多的国内经验介绍,并问及光源的位置。在这方面我们同济大学的同志做的工作还不多,曾一度用蜂窝式光斑牌作为接仪器,以便立即用电路通向记录仪,记下振幅曲线。甚至于想用三组接仪器来同时记录桥梁的竖向振动与扭转振动,
Since the publication of “Design Concept of Prestressed Concrete Diagonal Tension Bridge” (hereinafter referred to as “Concept”), I have been warmly received by readers and asked me to provide more information or discuss with me on certain issues in the text. Then the total answer is as follows: First, the laser measurement problems Some readers hope to see more of the domestic experience, and asked about the location of the light source. In this regard, we have not done much work with our comrades in Tongji University. Once we used a cellular optical spot card as an instrument to immediately lead the circuit recorder to the recorder and record the amplitude curve. Even want to use three sets of equipment to record simultaneously bridge vertical vibration and torsional vibration,
