摘要
通过天津市某大型地下式污水处理厂桩基础比选,探讨了建于液化场地的地下式污水处理厂的桩基础设计方案中,考虑PHC桩挤土消除液化的效应在规范及应用层面的可行性文中对该厂的钻孔灌注桩、PHC桩方案进行比较,发现在考虑挤土消除液化效应后,PHC桩基础方案在经济性上具有极大的优势。文中还介绍了该方案设计的过程,指出了该方案的关键技术点。
Based on the pile foundation comparison of a large underground sewage treatment plant in Tianjin,the feasibility of considering the soil compaction effect of PHC pile to eliminate liquefaction in specification and application level was discussed while designing pile foundation of underground sewage treatment plant built in liquefaction site.The bored pile and PHC pile scheme of the plant were compared.And it was found that the PHC pile foundation scheme has great economic advantages after considering the soil compaction effect of PHC pile to eliminate liquefaction.The design process of the scheme was also introduced in this paper,and the key points of the scheme were pointed out.
