摘要

本研究通过对6个现场案例进行分析,通过便携式动力锥贯入试验对受损加筋土墙的损伤原因进行识别,评估便携式动力锥贯入试验(DCPT)的现场适用性。现场使用了改进的动态混凝土渗透测试仪,可以进行超过6米的地面测量。将试验结果与标准侵彻试验(SPT)结果进行比较,并分析其相关性。通过对各种现场应用案例的分析,发现便携式动力锥贯入试验非常方便地应用于加筋墙损伤现场,并且DCPT可以通过连续识别地面强度,在识别挡土墙损伤原因和验证挡土墙稳定性方面发挥重要作用。此外,还发现动态圆锥体渗透测试的结果与标准渗透测试的结果在沙土中表现出N≒(1/3~2/3)·Nd的相关关系。

Analysis of Application Cases and Evaluation of Effectiveness on Portable Dynamic Cone Penetration Test (DCPT) to Identify the Deterioration Cause of Damaged Reinforced Earth Walls
In this study, a total of six site cases were reviewed to assess the site applicability of portable dynamic cone penetration test (DCPT) by identifying the cause of damage to the damaged reinforced earth wall using portable dynamic cone penetration test. An improved dynamic concrete penetration tester was used at the site to enable ground surveys of more than 6 meters. The test results were compared with the results of the standard penetration test (SPT) and the correlation was analyzed. Through the analysis of various field application cases, it was found that portable dynamic cone penetration test was very convenient to apply at the site of the damaged reinforced earth wall, and DCPT could play a major role in identifying the cause of damage and verifying stability of the retaining wall by continuously identifying the ground strength. In addition, it was found that the results of the dynamic cone penetration test and the standard penetration test showed a correlation of N≒(1/3~2/3)・Nd in sandy soil.
