摘要
本文通过对某高速公路水稳碎石基层裂缝的调查,从研究裂缝的分布入手,分析了施工时间、施工车辆行驶对裂缝的影响,抓住引起裂缝的主要因素,在基本符合实际的假定基础上,运用弹性理论及混凝土强度理论推导水稳碎石温度应力裂缝间距的计算公式,并对实际裂缝用计算公式进行了检验,提出了控制水稳碎石温缩裂缝的措施。
In this paper the authors analyze the cement treated crushed stone base cracks of one expressway to find out the main factors leading to the cracks.Based on the basically realistic presumption,elastic theory and concrete strength theory are used to deduce the equation to calculate the crack interval caused by cement treaded crushed stone temperature stress,and the equation to test actual cracks.The method of controlling temperature shrinkage crack is put forward.
