水泥稳定砂砾基层裂缝调查分析

CRACK INVESTIGATION AND ANALYSIS OF CEMENT STABILIZED GRAVEL BASE

为了研究水泥稳定砂砾基层施工期间产生裂缝的情况,在齐齐哈尔地区选择了5个路段,对水泥稳定砂砾基层在未铺筑沥青面层前,经第一个冻融循环作用后裂缝进行了实际调查,并运用SPSS软件的K-S检验对裂缝间距的数量变化趋势进行检验,另根据软件中的直方图和P-P图判断所选路段的裂缝间距样本是否符合正态分布。

In order to study during the construction of cement stabilized gravel base cracks the case, in the Qiqihar region to select the five sections. In the absence of paved asphalt surface before the cement stabilized gravel base has undergone a freeze-thaw cycle role. This paper investigated the actual cracks in cement stabilized gravel base case. Using SPSS software to test trends of the crack spacing. According to the histograms and the PP software to determine diagram distance between the cracks in the selected section of the sample is in line with normal distribution.
