本文主要根据沪嘉高速公路上试验路段的情况,结合室内试验的结果介绍粉煤灰的物理、化学、力学性能、施工工艺与效益分析。日试验路尚表竣工,成果是初步的,仅供参考。沪嘉高速公路全长15.9公里,是通往山东烟台的204国道的一段。设计车逮为120公里/小时,全部控制出入,立体交叉。路堤的平均高度2.7米,路堤最大高度为4米,路基边坡采用1:1.5,路基宽度26米。试验路段总计1.3公里,分布在沿线二个地段。路堤采用四种断面结构:纯灰、一层灰一层土、一层灰二层土和纯土。总用灰量为10万吨。 In this paper, mainly based on the Shanghai-Jiaxing-Expressway section of the trial conditions, combined with the results of laboratory tests to introduce the physical, chemical, mechanical properties of fly ash, construction technology and benefit analysis. The test road on the table is completed, the results are preliminary, for reference purposes only. Shanghai Jia highway length of 15.9 kilometers, is leading to 204 State Road, Yantai, Shandong section. Design car arrest is 120 km / h, all control access, three-dimensional cross. The average embankment height of 2.7 meters, the maximum embankment height of 4 meters, the use of subgrade slope 1: 1.5, 26 meters wide subgrade. A total of 1.3 km road section, located in two lots along the line. Embankment using four sections of the structure: pure ash, a layer of gray soil, a layer of gray soil and pure soil. The total amount of ash is 100,000 tons.
