摘要

目前,对于最常见的快速荷载桩试验(即静态荷载桩试验),工程师可获得的使用和方法指导有限。为完善粘性土静力试验分析,在冰碛垄上安装了全尺寸螺旋钻孔灌注桩并进行了试验。因此,在测试方法和分析方面提出了改进建议。在桩头安装一个加速度计,可以直接测量加速度,并验证位移测量和速度计算。在测试周期前后对桩进行高精度光学调平,可以更可靠地考虑多个加载周期。激光参考源与试桩的距离应足以避免表面波干扰。

Some observations on Statnamic pile testing
Limited guidance on usage and methodology is currently available to engineers for the most common rapid load pile test, known as Statnamic. In order to improve the analysis of Statnamic testing in clay soils a full-scale instrumented auger bored pile was installed and tested in glacial lodgement till. As a result, improvements have been suggested in the test methodology and analysis. The inclusion of an accelerometer at the pile head would allow direct measurement of acceleration and verification of displacement measurements and velocity calculations. High-precision optical levelling of the pile before and after test cycles would allow multiple loading cycles to be considered cumulatively with greater confidence. The separation of the laser reference source from the test pile should be sufficient to avoid surface wave disturbance.

期刊介绍: The objectives of the Association shall be the promotion of co-operation among geotechnical societies in SE Asia; and the assistance to member societies who have limited number of members. Now there is only one combined web titled: AGSSEA-SEAGS. SEAGS & AGSSEA encourage the submission of scholarly and practice-oriented articles to its journal. The journal is published quarterly. Both sponsors of the journal, the Southeast Asian Geotechnical Society and the Association of Geotechnical Societies in Southeast Asia, promote the ideals and goals of the International Society of Soil Mechanics and Geotechhnical Engineering in fostering communications, developing insights and enabling the advancement of the geotechnical engineering discipline.
