介绍潜堤护面工程质量的简易检测方法(轻潜水下探模).

变态防浪护面块体设计

从防浪护面工程的总体最优出发,通过理论推演和模型试验,导出了一组计算式。据此,提出了变态防浪护面块体的设计方法。变态块体在抗御与原型体块相同的波浪时,不仅可增加其稳定性,还可降低护面块体的排放厚度。因而,具有明显的经济效益。

A Project-Based Sustainability Rating Tool for Pavement Maintenance

Pavements require maintenance to prevent undue distress or to restore performance; however, pavement maintenance and its impacts do not receive enough attention in many cases, and are either ignored or treated as a low priority, Most current maintenance activities have budget issues and only focus on removing deteriorated pavement sections, Deferred pavement maintenance has impacts on the environment and on society, and may thus affect the costs associated with maintenance, A sustain- ability rating tool is a good way to list, explain, and evaluate such impacts, Various sustainahility rating tools have been developed for pavement; however, pavement maintenance has its own features that are different from those of the new construction, expansion, or reconstruction of pavements, This research project reviews nine sustainahility rating tools for pavement, although none of these tools fully describe maintenance features or can he directly applied to evaluate maintenance projects, A new sustainahility rating tool is then developed for pavement maintenance; this new tool can he used to evaluate individual projects and raise public awareness about the importance of pavement mainte- nance, Its details are described, and its use is demonstrated through an example to show the evaluation process and results,

高速公路预制混凝土空心砖格网式护面的应用研究

金丽温高速公路蜿蜒延展于浙江中部和西南部高山峡谷地带,沿线挖方边坡很多,边坡的护面显得极为重 要。为了确保边坡的长期稳定和沿线护坡的景观协调,本工程采用了多种护面形式的和谐变换,其中预制 空心砖的格网式护面效果颇为引人注目,具有一定的观赏价值。

小型构件预制施工技术总结

小型预制构件是高速公路不可或缺的部分,主要应用于排水工程、防护工程及护面工程。文章中项目的排水工程包括边沟、排水沟、急流槽、导流坝等,主要起到主线内的排水作用;防护工程分为拱形骨架路基防护及六角空心块桥头与锥坡防护,其中拱形骨架主要起防护路基边坡的作用,六角空心块主要起桥头及锥坡防护作用;挖方段护面工程主要采用小型预制构件护肩板Ⅱ进行安装,主要起路肩防护、排水作用。
