佛山市顺德区大良镇某砌石重力式挡土墙安全性评估研究

Research on the safety assessment of a Masonry Weight Retaining Wall in Daliang town of Shunde district of Foshan city

基于佛山市顺德区大良镇某砌石重力式挡土墙具有如下特点:挡土墙年代久远、设计施工资料遗失、长期未维护、安全性存疑等,研究组提出了综合评估该砌石挡土墙安全性的方法,为该挡土墙的加固、重修及边坡治理的设计提供相关依据。根据相关规范[1-3],针对待评估挡土墙进行了资料收集、实地踏勘、表观缺陷调查、墙体施工质量检查、构造措施检查及挡土墙稳定性验算等工作,综合评估该挡土墙的安全性,结论为:该挡土墙存在较大安全隐患,工程建议为拆除、重建。

Based on a masonry weight retaining wall in Daliang town of Shunde District of Foshan city has the following characteristics: the retaining wall was builded for a long time, lost design and construction data, long term unmaintained,security doubt and so on. The research group has put forward a comprehensive method to assess the safety of the masonry retaining wall, providing the relevant basis for the design of retaining wall reinforcement, repair and slope treatment.According to the relevant rules, for the assessment of retaining walls were data collection, investigation, apparent defect investigation, wall construction quality inspection, and checking calculation the stability of retaining structure wall etc.Comprehensive assessment of the safety of the retaining wall, the conclusion is that the retaining wall has a great potential safety hazard, and the project is suggested to be demolished and rebuilt.
