摘要:

某工业砖砌圆筒仓结构投入使用后外仓壁出现多处竖向裂缝,现场对该结构开裂情况和材料强度进行检测,计算不同高度仓壁承受的环向拉力和仓壁的环向承载力,综合分析可知,该筒仓结构设计存在显著缺陷,仓壁环向承载力不足是其开裂的主要原因。基于上述结果,提出一种加固处理方法,在原砖仓壁内表面浇筑钢筋混凝土形成剪力墙结构,代替砖仓壁承受储料引起的环向拉力,经过分析计算,确保了环向承载力满足要求。

After an industrial brick cylindrical silo structure was put into use, multiple vertical cracksappeared on the outer silo wall. On⁃site detection was carried out on the cracking condition of thestructure and the material strength. The circumferential tension borne by the silo wall at different heightsand the circumferential bearing capacity of the silo wall were calculated. Comprehensive analysis showsthat: The silo structure design has significant defects, and the insufficient circumferential bearingcapacity of the silo wall is the main cracking cause. Based on the above results, this paper proposes areinforcement treatment method,which involves casting a reinforced concrete shear wall structure on theinner surface of the original brick silo wall to replace the brick silo wall in bearing the circumferentialtension caused by stored materials. Through analysis and calculation, it is ensured that thecircumferential bearing capacity meets the requirements.
