［提要］ 針對(duì)蛋形消化池結(jié)構(gòu)受力的復(fù)雜性、特殊性及結(jié)構(gòu)本身的尺寸限制，提出了沿環(huán)向與子午向配筋和沿45°傾斜方向配筋兩種預(yù)應(yīng)力設(shè)計(jì)方案，通過對(duì)兩種方案的比較，確定了沿環(huán)向與子午向配筋方案，該方案較好地解決了蛋形消化池結(jié)構(gòu)在各種受力工況下的使用要求，能很好地滿足預(yù)應(yīng)力體系對(duì)結(jié)構(gòu)構(gòu)造的要求。

Mechanical Analysis of Eggshaped Digester Tanks and Selecting Prestressing Methods/Liu Yaowu,Li Chuanping,Zhang Baohe(Shanghai Giant Prestressing Engineering Corporation Limited,Shanghai 200235,China)
Abstract:Considering eggshaped digester tanks on mechanical complexity and limit of dimensions,two different prestressing methods are presented for laying prestressing tendons on longitude,latitude and 45 degree.Based on the comparison of the two methods,a scheme of laying prestressing tendons is drawn on longitude and latitude.The scheme can satisfy the workability of eggshaped digester tanks on different working conditions and the requirements of construction.
Keywords:eggshaped digester tanks; prestressing tendon; mechanical analysis
