1941年京塘公路杨家堤至汗沟镇之间的一段路面,是用竹筋混凝土铺装的。这段路面经过长期使用,直到1950年还保持着原来的状况,力国内外研究和立用竹筋混凝土提供了一些资料。我们知道,混凝土路面工程中所用的混凝土,以要求抗弯强度为主。因为混凝土路面是作为一种板型构件设计的,它本身除了能够有足够的耐磨面层来承受各种车辆轮胎的磨耗外,还要有足够的伸张应力来抵抗由于面层所来的车辆荷重达到平衡。要达到这个目的,必须使混凝土板有相当高度的抵抗穹曲的能力,才能保持板的平衡荷重而免于破裂。同时,由于混凝土本身收缩膨胀的因素,板会出现裂缝。要克服这些缺点,并增加混凝土板抵抗弯曲强度的办法,就是在混凝土板内增加具有伸张应力和弹性模量较大的钢筋或竹筋。由于竹筋具有这种性能,并且成本比钢筋低廉,因 In 1941, a section of pavement between Yangjiatan and Karstogou on Jingtang Highway was paved with bamboo tendon concrete. After long-term use of this road surface, it maintained its original status in 1950 and provided some information on researching and establishing bamboo reinforced concrete at home and abroad. We know that concrete used in concrete pavement works mainly to require flexural strength. Because the concrete pavement is designed as a plate-type component, in addition to its ability to have enough wear-resistant finish to withstand the wear and tear of a variety of vehicle tires, but also have sufficient stress to withstand the surface due to the vehicle Load balance. To achieve this goal, concrete slabs must have a fairly high degree of resistance to the ability of the domes to maintain their balanced load against rupture. At the same time, due to shrinkage expansion of concrete itself, the board will crack. To overcome these shortcomings and increase the flexural strength of concrete slab approach is to increase in the concrete slab with tensile stress and greater modulus of elasticity of steel or bamboo. Because bamboo tendons have this kind of performance, and the cost is lower than that of reinforced bar
