摘要
该文就确定大直径灌注桩端阻力深井载荷试验的必要性，深井载荷试验的设备、试验与资料分析整理的要点进行了探讨。特别是侧壁支撑系统能解决深井试验中遇到的诸多难题，能较好地完成测试工作，为工程设计提供可靠的依据。
The paper confirms the necessity of conducting the plate load test in deep test pit to determine the end bearing of large diameter cast - in - place pile, makes discussions on the essentials of the equipments, test procedure and analysis of data collation. Especially, many difficult problems met in the deep pit test can be solved by the lateral wall retaining system. It can better accomplish the testing work and present reliable has for engineering design.
