以前,我省修建的直立式码头,都是砌石行工重力式结构。基础的施工,均采用围堰抽水、明挖砌筑方案。 但是,随着码头建筑高度的加大,砌体体积和基底应力也相应加大。从我省近几年所建的砌石行工码头的实际资料分析,按每延米计算,当码头建筑高度增加1米,砌体体积增加4.22～5.23米~3;对于高度超过10米的砌石圬工码头,基底应力在45～
In the past, the upright wharf built in our province was constructed with masonry gravity structure. The basic construction, are cofferdam pumping, dig dig masonry program. However, with the increase of the height of the wharf, the volume of the masonry and the stress of the basement also increase correspondingly. According to the actual data analysis of the masonry dock constructed in recent years in our province, the height of the dock building increases by 1 meter and the volume of the masonry increases by 4.22-5.23 m ~ 3 according to the calculation per meter. For the height exceeding 10 meters Stone masonry dock, the substrate stress at 45 ~
