At that time, groups of Chinese traders crossed this road with the help of camels at the risk oflosing their own life in the desert; venturing their trade in westerncountries. Nowadays, sands have covered this road and soundfrom camel bells has died out for a long time, but the pioneeringspirit of Chinese trade forerunners has been passed to us despitethe lapse of time. As a trade platform of China’s textile and apparelenterprises, the Sub-Council of Textile Industry, China Council forthe Promotion of International Trade (CCPIT TEX) was consideredas an intangible Silk Road that provides trade opportunitiesthrough organizing expo. and exhibitions.展开更多
为提高水稳层施工质量并延长市政道路工程的使用寿命,以某市政道路工程项目为例,提出基于GM-BP组合监测的水稳层施工质量智能控制方法。根据工程需求,选择等级在32.5以上的普通硅酸盐水泥作为主要原材料;将混合料摊铺在作业面上,进行混...为提高水稳层施工质量并延长市政道路工程的使用寿命,以某市政道路工程项目为例,提出基于GM-BP组合监测的水稳层施工质量智能控制方法。根据工程需求,选择等级在32.5以上的普通硅酸盐水泥作为主要原材料;将混合料摊铺在作业面上,进行混合料摊铺厚度调整与摊铺速度控制;碾压施工按初、复、终三个阶段进行,根据工程需求设计市政道路工程水稳层碾压施工;在此基础上,采用灰色神经网络(Grey Model with Back Propagation,GM-BP)监测施工关键参数,实时进行施工调整,对道路工程进行接缝处理,之后对其进行养护,由此完成施工质量智能控制。分析结果表明:设计的施工质量智能控制方法应用效果良好,可以确保道路工程压实度、平整度、纵段高程、横坡等指标通过质量验收,使施工后的道路实际强度满足施工强度代表值要求。展开更多
