| 中文摘要: |
| 本文通过苏通大桥16根试桩的承载力自平衡测试，介绍了自平衡法静载试验的原理和方法．并根据测试结果，分析了影响桩基承载力的控制因素，比较了压浆前后承载力的变化情况，提出了有效的措施．为基础的优化设计和后续施工提供了保证。 |
| 英文摘要: |
| This paper presents the principle and method of self-balanced load test by testing the capacity of sixteen trial bored piles of Sutong Bridge. In addition, it analyzes the controlling factor which influences pile bearing capacity based on testing results; It also introduces some effective measures after comparing the varied capacity pre- and post-grouting, which guarantees optimized design and subsequent construction. |
