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.
Research on Quality Control of Water Stable Layer Construction in Municipal Road Engineering Based on GM-BP Combined Monitoring
In order to improve the quality of water stable layer construction,and prolong the service life of munic-ipal road engineering,an intelligent control method for water stable layer construction quality based on GM-BP combined monitoring is proposed,taking a certain municipal road engineering project as an example.According to the needs of the project,ordinary Portland cement with a grade above 32.5 is selected as the main raw material;spread the mixture on the working surface,adjust the thickness of the mixture paving and control the paving speed;rolling construction is carried out in three stages:initial,secondary,and final stages,and the rolling con-struction of the water stable layer of municipal road engineering is designed according to the engineering require-ments;on this basis,Grey Model with Back Propagation(GM-BP)is used to monitor key construction parame-ters,make real-time construction adjustments,treat road engineering joints,and then maintain them,thus complet-ing intelligent control of construction quality.The analysis results indicate that the designed intelligent control method for construction quality has a good application effect,which can ensure that the compaction,flatness,ver-tical section elevation,cross slope and other indicators of road engineering pass quality acceptance,so that the actual strength of the road after construction meets the requirements of the representative value of construction strength.
