基于汽车坡道圆曲线测设及标高控制关键技术研究

Study on Key Technologies of Measuring Circular Curve and Controlling Elevation Based on Automobile Ramp

目前,地下车库在房屋建设中已经必不可少,以德丰大厦工程为实例,根据地下汽车坡道(直线曲线混合坡道)施工中常出现的标高控制、模板支护难度、环形转弯处横向及纵向坡度的控制,以及用直线段代替圆弧段在工程实际中的应用及误差分析等,来探讨在工程实际中处理圆曲线的相关问题。

At present,the underground garage has been essential in housing construction. Taking Defeng building project as an example,the matters related to circular curve in engineering practice,as the underground car ramp（ mixed ramp by straight line and curve） encountered in construction elevation control,template supporting difficulty,annular corner transverse longitudinal slope control,and the error analysis of using straight line segments instead of curved ones in engineering are discussed.
