摘　　要：提出了一种新的检查井盖维修思路,以实际损坏率为指标,对安装槽这一关键因素进行了研究。结果表明,在其他因素保持不变的情况下,当安装槽宽度从20 cm减少至1 cm时,井盖年损坏率从38%降至5%。当安装槽宽度为1 cm、高度比路面低1 cm时,井盖年损坏率进一步降低(从5%降至2%)。通过降低安装槽宽度和高度,避免检查井盖维修过程中的薄弱环节(安装槽)与荷载产生直接接触,能有效避免安装槽受力不均,从而提高检查井盖的寿命,防止出现反复性井盖病理危害。A new perspective on manhole cover maintenance was presented.Taking the damage rate as the index,the key factor of installation groove was innovatively studied.It was found that the annual damage rate of manhole cover has dropped from 38%to 5%in the same situation when the installation groove width was reduced from 20 cm to 1 cm.Besides,the annual damage rate has decreased further from 5%to 2%,when the installation groove was 1 cm wide and 1 cm lower than the pavement.By reducing the width and height of the installation groove and avoiding direct contact between the weak link(installation groove)and the vehicle load in the manhole cover maintenance process,it can effectively avoid the uneven force of the installation groove,thereby improving the service life of the manhole cover and preventing the occurrence of repeated manhole cover pathological hazards.
