【摘要】：道路的通畅,对于提升人民生活水平,方便人们出行及经济社会活动,起到非常大的作用,省道211线瓦斯沟至姑咱段地处四川省康定县瓦斯沟至姑咱镇之间,距成都公路里程约360km,与国道G318公路、省道211公路相连,交通条件非常重要。为进一步完善省干线公路网,改善丹巴县及道路沿线地区交通条件,拟对省道211线瓦斯沟至姑咱段路段进行改建。本文通过运用项目质量管理以及进度管理的有关理论对省道211线瓦斯沟至姑咱镇段改建项目进度和质量管理进行优化研究,主要工作如下:首先,介绍了项目进度管理和项目质量管理,包括其定义、其主要工作内容,也介绍了具体的管理方法。其次,分析了省道211线瓦斯沟至姑咱镇段改建项目的概况,包括项目简介,项目建设工程量及条件,项目建设目标,项目组织机构,项目实施情况,分析了项目中存在的进度问题,包括施工前期工作进度相对滞后的原因分析,现场质量管理水平低,质量控制措施不到位,盲目追求工程进度导致工程质量出现明显问题等,以及项目质量管理中存在的问题,包括各个分包单位则为了实现利润的最大化,对合同中要求的质量予以降低,这就对项目管控的难度增大,项目实施前的调查工作做得不够细致,项目的地理位置、相应的法规政策以及人文因素等对项目质量的影响,项目进度对质量的影响等。最后,运用计划评审技术,关键路径法,甘特图法等方法,对省道211线瓦斯沟至姑咱镇段改建项目的进度进行了优化,包括重新进行进度规划,项目工作任务分解,项目活动排序及工期估算。项目里程碑计划,项目进度计划表及甘特图,关键路线确定等,并在详细项目进度计划的基础上,提出项目进度计划监控,项目进度动态调整及项目进度管理保障措施等方案,并对项目的质量进行控制:建立项目质量保证体系,分为思想保证体系,组织保证体系,目标管理保证体系,生产过程质量保证体系,质量检查保证体系,质量信息保证体系,经济保证体系,确保项目实施过程中,思想、组织、经济、质量监督等全方位保证。完善项目质量保证措施,加强质量教育,技术培训,完善质量信息网络等,并从工艺控制措施,工程材料控制措施,施工操作控制措施,工程款支付控制措施等多方位提出项目质量控制方案。
[Abstract]:The smooth road plays a very important role in improving people's living standards, facilitating people's travel and economic and social activities. The section from Wasgou to Guzan on the provincial road 211 is located between Vasgou and Gouzan town in Kangding County, Sichuan Province. Chengdu highway mileage is about 360 km, connected with national highway G318, provincial highway 211, traffic conditions are very important. In order to further improve the highway network of provincial trunk lines and improve the traffic conditions of Danba County and areas along the road, the section from Vasgou to Guzan of provincial highway 211 is proposed to be reconstructed. Based on the theory of project quality management and schedule management, this paper makes an optimization study on the progress and quality management of reconstruction project from Wasgou to Guzan Town on the 211 line of provincial highway. The main work is as follows: first of all, This paper introduces the project schedule management and project quality management, including its definition, main work contents and specific management methods. Secondly, it analyzes the general situation of the reconstruction project from Wasgou to Guzan Town on the 211 line of provincial highway, including the project profile, the quantity and conditions of the project construction, the construction target, the organization of the project, and the implementation of the project. This paper analyzes the progress problems existing in the project, including the cause analysis of the relative lag of the work progress in the pre-construction period, the low level of on-site quality management, the lack of quality control measures in place, and the blind pursuit of the project progress, which leads to obvious problems in the engineering quality, etc. And the existing problems in project quality management, including each sub-contractor in order to maximize profits, to reduce the quality required in the contract, which increases the difficulty of project control. The investigation work before the implementation of the project is not meticulous, the geographical location of the project, the corresponding regulations and policies, the impact of humanistic factors on the quality of the project, the impact of the project schedule on the quality of the project, and so on. Finally, using the methods of plan evaluation, critical path method, Gantt chart and so on, the progress of the reconstruction project from Wasgou to Guzao Town on the 211 line of provincial highway has been optimized, including re-progress planning and the decomposition of the work tasks of the project. Project activity sequencing and duration estimation. Project milestone plan, project schedule and Gantt chart, key route determination, etc. On the basis of detailed project schedule plan, the project progress plan monitoring, project schedule dynamic adjustment and project progress management safeguard measures are put forward, and the project progress plan monitoring, project schedule dynamic adjustment and project progress management safeguard measures are put forward on the basis of detailed project schedule. And to control the quality of the project: to establish the project quality assurance system, divided into ideological assurance system, organizational assurance system, objective management assurance system, production process quality assurance system, quality inspection assurance system, quality information assurance system. Economic guarantee system, to ensure the implementation of the project, ideological, organizational, economic, quality supervision and other omni-directional assurance. Improve project quality assurance measures, strengthen quality education, technical training, perfect quality information network, and from the process control measures, engineering materials control measures, construction operation control measures, etc. Project payment control measures and other multi-dimensional project quality control scheme.
