轻型动力触探试验在吉林省中部城市供水工程基槽验收中的应用

Application of light dynamic penetration test in foundation tank acceptance of Central City Water Supply Project in Jilin Province

吉林省中部城市引松供水工程为大型引调水工程,主要施工方式为开挖埋管回填。地基验收是工程必不可少的环节,实际工作生产过程中发现,施工期轻型动力触探数值远小于勘察期试验数值,根据轻型动力触探定量判断是否满足验收普遍存在争议。现特对此现象进行讨论。

The Central City Water Supply Project of Jilin Province is a large-scale water diversion project, and the main construction method is excavation and backfilling of buried pipes. Foundation acceptance is an essential part of the project. It is found in the actual work and production process that the light dynamic penetration value during the construction period is far less than the test value during the investigation period. It is generally controversial to judge whether the acceptance is satisfied according to the light dynamic penetration quantity. This phenomenon is now discussed.
