Aiming at the problem of expansive scale of expansive soils,the paper constructs a new interval incidence function.
针对膨胀土胀缩等级分类问题,构造了一种新的区间关联函数,提出了"分类特征体现度越大,权重越大"的权重计算原理,给出了一种新的变权计算方法,将单指标关联函数的最大值作为其评价类的靶心坐标,根据样本与靶心的贴近度,对样本进行分类。
The swell-shrinking stress of porous concrete base was also calculated and the predication method of critical temperature difference and the calculation method of joint space under base cracking were put forward.
根据一维热传导假设,求解水泥混凝土路面的温度场,计算得出多孔混凝土基层顶面的翘曲应力;求解多孔混凝土基层的胀缩应力,提出基层开裂临界温度差的预估方法以及基层开裂时接缝间距的计算方法;推荐了常见路面结构厚度范围多孔混凝土基层的接缝间距。
