In this paper,the mechanical properties of the old PCC pavement structure overlaid with AC was analyzed with ANSYS,a software for finite element analysis,and the influence of interlayers,depth of AC-overlay and modulus of AC-overlay was taken account.According to the study it could be concluded that in order to retard the reflective cracking the interlayer should be put below the overlayer and the interlayer of high modulus can take effect well.

结合试验路实体工程，采用有限元方法分析了土工布、玻璃纤维网对旧水泥混凝土路面沥青混凝土加铺层复合式路面结构的内力影响，发现为防治旧PCC路面的接缝/裂缝在AC加铺层内产生反射裂缝，宜在加铺层底部铺设夹层，且模量较大的玻璃纤维网效果更好。

Due to the luck capability in the floating-point operation of PCC, the interpolation method most compatible with the axial-flow adjustable-blade water turbine collaboration can be confirmed, compared with the other collaboration interpolation method. The method is improved on the basis of regular linearity interpolation. It increases the precision of interpolation and rapidity of operation.

2：针对PCC浮点运算能力不够强的特点，通过对比多种协联插值方法，寻找出适合在轴流转桨式水轮机协联运行中运用的插值方法，该方法在常规线性插值的基础上进行了改进，做到了在提高插值精度的同时，又兼顾了一个较快的运算速度。

Experimental results showed that the CPF improved the retention of precipitated calcium carbonate filler significantly. With 0.9% CPF (based on oven-dry pulp), the retention of PCC increased from 57.53% to 72.21%. The physical properties of paper were also slightly improved. The tensile strength and burst strength of the paper with CPF were higher than those with CPAM.
