作者： Yancang Li juanjuan Suo Shujing zhou Hebei University of Engineering Handan 056038 China

To overcome the shortcomings that there are few feasible methods and models in the comprehensive assessment on the system reliability of cable-stayed bridges, a mathematical tool-the unascertalned measure was introduced. First, the basic knowledge of the Unascertained Sets was introduced briefly. Second, the unascertained measure was defined and the comprehensive assessment model was set up. Then the method was introduced to the assessment of the system reliability of a cable-stayed bridge located in Tianjin City. Engineering practices shows that the method can complete the assessment systematically and scientifically without any assumption. The work has significance in theory and practice for the comprehensive assessment of bridge engineering.

江山坐唱班作为浙西农村广泛流传的一种代表性的民间艺术形式,反映了浙西农村鲜活的社会风俗和民众生命样态。主要为农户俗事服务,通过不同的曲调和乐器组合,体现人们在不同环境的不同心情,营造不同礼仪场面的环境氛围。作为非物质文化遗产关注的对象,大多班社处于自生自灭的状态,要做好保护工作,一要完善保护机制;二要探求文化创新;三要尊重艺术自身发展,重视培养传承人。

为控制城市初期雨水径流污染,以及助力排水系统提标,雨水调蓄设施的应用日益广泛。然而,在中心密集城区,调蓄设施的选址和运维逐渐成为一个难题。以上海某排水系统为例,提出了在系统末端结合雨水泵站及河底空间建设调蓄设施的技术方案。方案通过自清洗流道设计,实现少维护/免维护的目标;通过建设功能综合体,将涉及常规功能、拓展功能、恢复功能的三类设施集约化布置,并可实现“转输处理+就地处理”复合模式。研究还提出了针对河底调蓄建设方案进一步推广应用的相关建议,可为城市密集区调蓄设施的建设提供参考借鉴。
