摘要(Abstract):

介绍了因相邻深基坑开挖导致的地基不均匀沉降造成生化池开裂后的检测情况,并提出压密注浆及体外预应力加固处理方案,提出了预应力加固法加固量和预应力筋温度应力等计算方法,经6个月的沉降观测,结果表明,采用的加固方法是合理有效的。
A scheme of examining-measuring and strengthening of biochemistry pool introduced after its unequal settlement and appearance of cracks of the structure and etc is introduced,and the quantity of external pre-stressed strengthening and the temperature stress of external pre-stressed bar are put forward.The strengthened settlement is observed for 6 months,and the result makes out this scheme is feasible and available.
