采用三维有限元分析方法,计算分析了具有接缝的旧水泥混凝上路面上沥青加铺层在行车简载作用下应力随板底脱空的变化情况,从理论上深入研究了不同板底脱空对沥青加铺层反射裂缝的影响,阐述了板底脱空对沥青加铺层荷载应力的影响。
2.
In order to solve the problem that the relationship among the cavity,the deflection difference and the degree of pumping was not explained definitely and the domestic and overseas research is little,the deflection index for the cavity beneath slabs was calculated theoretically based on Yantai-Weihai highway testing section as backing project.
针对弯沉差和唧泥程度与板底脱空的关系在规范中并未有明确说明,且国内外研究也较少的情况,以烟台—威海高速路试验段为依托工程,对板底脱空的弯沉评价指标进行了理论计算,采用贝克曼梁弯沉仪(BB)和落锤式弯沉仪(FWD)对比测量,计算了同板板中、板边中点、板角弯沉差;通过对唧泥观测记录统计分析,提出了根据唧泥高度判别脱空程度的评定标准,分析了唧泥高度的影响因素及变化规律,结合实际钻芯检测数据,建立了唧泥高度与板底脱空量的对应关系。
