【摘要】：作为修复加固的基础性工作,高桩码头受灾以后结构安全性的检测评估十分关键。上部结构损坏情况相对来说易于检测和加固处理,难度较大的是桩基损坏情况的准确检测和评估。不同于施工过程的常规检测,目前颁布实施的相关规范并不适用,很多时候检测人员无所适从。同时,为了确保码头结构的安全性与耐久性,尽快恢复码头的正常运营,应及时对下部受损基桩进行修复加固。不同于常规的修复加固工程,受到梁板等上部结构、潮位、水流等诸多因素影响,下部受损基桩的修复加固难度大,特别是大量断桩的修复加固更加困难。结合多起灾后高桩码头检测、评估与修复加固的成功案例,本文详细阐述了桩基础检测与评估的具体方法与步骤,详细介绍了受损基桩的修复加固设计方法。同时在文末列举了两个工程实例,可为相关工程技术人员提供参考。
[Abstract]:As the basic work of repairing and strengthening, the detection and evaluation of structural safety after the disaster of high pile wharf is very important. The damage of superstructure is relatively easy to detect and reinforce. It is very difficult to accurately detect and evaluate the damage of pile foundation. Different from the conventional inspection of construction process, the relevant regulations promulgated and implemented at present are not applicable, and most of the time the inspectors are at a loss. At the same time, In order to ensure the safety and durability of the wharf structure and restore the normal operation of the wharf as soon as possible, the damaged foundation pile should be repaired and strengthened in time. Under the influence of water flow and many other factors, it is difficult to repair and reinforce the damaged foundation pile in the lower part, especially for a large number of broken piles. Combined with the detection of high pile wharf after many disasters, the successful cases of repairing and strengthening have been evaluated and repaired. In this paper, the concrete methods and steps of pile foundation inspection and evaluation are described in detail, and the design method of repairing and strengthening the damaged foundation pile is introduced in detail. At the end of this paper, two engineering examples are listed, which can be used as reference for relevant engineers and technicians.
