一、引言多年来,在铺筑水泥混凝土路面时,总要考虑它由于温度变化而会产生膨胀或收缩,从而发生拱胀或开裂。因此,采取设置胀缝和缩缝的办法以图解决这类问题,并用以防止混凝土版的破坏。但是实践证明,设置这样的接缝,特别是胀缝,并不能解决混凝土版的破坏问题,相反,由于施工、养护和运行等原因,使胀缝成为最影响行车和最 I. Introduction Over the years, paving the cement concrete pavement, always consider it due to temperature changes will produce expansion or contraction, which occurred in the expansion or cracking. Therefore, to set the expansion joint and shrinkage approach to solve these problems, and to prevent the destruction of concrete version. However, practice has proved that setting such seams, especially expansion joints, can not solve the problem of concrete plate destruction. On the contrary, due to reasons of construction, maintenance and operation, expansion joints become the most influential driving and most
