【摘 要】半埋式超长水池结构的设计是在我国城市水处理系统逐步发展下提出的适应现今城市发展的设计。随着我国水处理系统的不断完善,其基础设施需要跟上时代发展的步伐,所以半埋式超长水池混凝土结构越来越多地出现在建设项目当中。论文重点关注不设缝水池结构,提出通过采取相应的措施实现了半埋式超长水池结构不设缝设计,希望有效解决半埋式超长水池结构中的裂缝问题。
【Abstract】The design of semi-buried super-long pool structure is put forward under the gradual development of urban water treatment system in China, which is suitable for today's urban development. With the continuous improvement of water treatment system in China, its infrastructure needs to keep up with the development of the times, so more and more semi-buried super-long pool concrete structures appear in construction projects. This paper focuses on the pool structure without joints, and proposes that the design of semi-buried super-long water pool without joints is realized by taking corresponding measures, hoping to effectively solve the problem of cracks in the semi-buried super-long pool structure.

1 半埋式超长水池结构不设缝设计概述
相较于全埋式超长水池结构不设缝设计,半埋式超长水池结构不设缝设计的应用范围较窄。超长水池结构不设缝往往容易开裂,为了满足使用条件,在进行建设时往往使用补偿收缩混凝土。同时,为了防止由于长度过长,而增加结构的不稳定性,在生产工艺中往往运用预应力技术,先进的生产工艺能够推进项目质量的提升,所以这些措施能够显著地延长结构的使用年限。但是当水池结构长期使用时仍可能导致出现开裂现象。所以在设计时,超长水池结构不设缝的应用较少,这是为了防止后期维护难度增大。但是半埋式超长水池结构中不设缝设计拥有着独特的优势。一般来说,设缝后容易造成水池整体的结构稳定性较差,对于大型水池来说,设置多道伸缩缝会进一步复杂化抗震措施。……
