海南省公路工程质量监管体系分析

海南省多数分部工程质量水平低于全国水平,尤其桥梁工程质量抽检合格率不高且波动大,一些分项工程质量指标也存在明显差距.问卷调查的线性逐步回归法分析表明:工程实体和投入要素的监控、质监体制和网络的健全、质量激励与约束机制的完善等是质量主要影响因素.实地考察和深度访谈发现业主、施工、监管等主体相互制衡机制缺位,参建单位质保体系不能有效运行,社会监督渠道不通畅.为此,建议构建"3+2+1"的质监主体制衡和协作架构,开放和规范监理检测市场,完善以承包商和从业人员为核心的质量边际激励约束机制,完善参建单位质量保证和监督系统,引导社会多元力量参与监督.

Quality supervision system analysis for highwayengineering in Hainan province

Analysis on the quality data collected by traffic quality supervision department shows that most of Hainan Province part project quality level is lower than the national average.Especially in bridge engineering quality sampling qualified rate is not high and volatile, and some sub project quality indicators also have significant gaps.The result, that was gotten by using questionnaires survey and linear stepwise regression analysis, show that the main factors of influencing the highway engineering quality in the province include that monitoring of engineering entity and input factors,improvement of quality supervision system and network,perfection of quality incentive and restraint mechanism etc.The questionnaires survey and interviews investigation show the lack of balance mechanism among the owner,construction,supervision units,the lack of quality assurance system of construction units and the lack of effective social supervision channel.Therefore, some methods were proposed which include construction of "3+2+1" highway quality supervision balance and coordination architecture system,opening and standardization of supervision and test market,perfection of marginal quality incentive and restraint mechanism taking contractors and employees as the core,improvement of quality assurance and supervision system in construction unit,guiding of the social forces to supervise.
