摘要:
本文在玻璃纤维增强水泥(混凝土)基本力学性能试验的基础上给出了城市道路中玻璃纤维混凝土井盖在垂直荷载作用下的试验结果.试验研究表明,采用合理的工艺和配比制作的玻璃纤维混凝土井盖开裂荷载明显推迟,构件达到极+限承载力以后的变形能力大,延性好,有较好的韧性和吸能性.长达两年的玻璃纤维混凝土井盖的路用试验表明,用这种方法制作的井盖可满足城市现行各级道路各类车辆荷载的要求,价格也较便宜,有明显的社会经济效益.
Abstract:
This article gives the test results of the glass fiber concrete manhole cover under the action of vertical load on the basis of the basic mechanical performance test of glass fiber enhancement cement (concrete) basic mechanical performance test. The test research shows that the cracking load of the glass fiber concrete manhole cover with reasonable process and ratio of the proportion is significantly delayed. Higher ability, good delay, and good toughness and energy absorption. The two -year -old glass fiber concrete manhole cover of glass fiber covering shows that the manhole cover made by this method can meet the requirements of various types of vehicle loads at all levels of roads in the city, and the price is cheaper, with obvious socio -economic benefits.
