上海郊区北松线(闵行经北桥至松江)公路上的K10+320石台石盖版涵洞,净孔径2米,石盖版的厚度只有27厘米(花岗石)盖版顶面至路肩顶面的填土高也只有15厘米。而北松线系主要交通路线,路线的荷载等级为汽—8级。目前通行的车辆大都是吉斯150型,解放牌、大道奇、奇姆西等重车,每昼夜行车密度达40～100辆次。且常有上海某厂的太脱拉牌10轮重车通过(太脱拉牌柴油车厂定载重为10.24吨,空车重量8.43吨,总重量18.67吨,后轴两支,每支后轴负荷7.4吨)。而这种结构能够适应,乍看起来甚感奇特。所以特地把它的结构尺寸精确量下,并验算了它的最危险的
The K10 + 320 stone bench cover culvert on the north suburb of Shanghai (Minhang via Beiqiao to Songjiang) has a net aperture of 2 meters and the stone cover plate has a thickness of only 27 cm (granite) top to the top of the road shoulder The fill height is only 15 cm. The North Pine Line Department of the main traffic routes, routes load level vapor -8 level. Currently most of the vehicles passing the Guice 150, Jiefang card, Avenue Dodge, Kym West and other heavy vehicles, driving density of 40 to 100 vehicles per day and night. And often a Tai Lara factory in Shanghai 10-wheel heavy truck through the (Taylor pull licensing diesel depot set load of 10.24 tons, empty weight of 8.43 tons, the total weight of 18.67 tons, two rear axle, each rear axle load 7.4 tons). And this structure can adapt, at first glance it is very strange. Therefore, it is precisely the size of its structure under the precise amount, and checked its most dangerous
