[提要] 山東省兗州市污水處理工程是國家實(shí)施淮河流域治污、南水北調(diào)戰(zhàn)略東線工程的重要組成部分，采用吸附-生物氧化二級(jí)處理法。其污泥消化池內(nèi)含混合泥漿沼氣，側(cè)壓力大，構(gòu)筑物整體采用后張無粘結(jié)預(yù)應(yīng)力技術(shù)，在較好地滿足使用功能要求的前提下成功地降低了工程成本。
[關(guān)鍵詞] 后張 無粘結(jié) 鋼絞線 標(biāo)準(zhǔn)值 屈服強(qiáng)度In the project of pollution control in Huaihe valley and the eastern line of trans ferring water from south to north strategy, the sewage disposal item in Yanzhou city is an important portion. In this item, we adpoted the absorption and secondary bio-oxigenation technique. Methane is produced during the mud dispose process, which would exert high side pressure to the pool. In the construction of the pool, the integral post-tensioned prestressed technique is used to cut down the expense.This experience is a good exploration in the improvement of this technique.
Keywords: post-tensioned; unbonded; tendon; standard value; yield strength
