摘要: 近年来,刚性桩复合地基处理方法在路堤软基加固工程中得到越来越广泛的应用。主要介绍了 TC 桩及其桩承式路堤系统的应用。 TC 桩具有加固效果好、处理深度深、工期短、质量便于控制、造价合理等优点,在对沉降稳定要求较高的路堤软基加固工程中逐渐得到应用。在介绍 TC 桩施工工艺的基础上,通过 TC 桩在某城市快速路软基加固工程中的应用,对单桩竖向静载荷试验和弯沉试验结果进行分析,说明 TC 桩的应用非常成功,试验结果可为 TC 桩及其复合地基理论研究提供参考。Abstract: The rigid pile composite foundation has been widely applied in soft ground treatment in recent years. The piled embankment system of TC piles, which belong to the rigid pile composite foundation, is introduced. It has been applied in some soft ground treatment of embankment for its advantages of better stabilizing effect, short construction period, better quality, economy, etc. Based on introducing the construction technology of TC piles and its application in a road engineering, the results of static load tests and deflection tests are analyzed. It is shown that the application of TC piles is feasible. It may provide reference for the theoretical researches on TC piles and composite foundations.
