摘要
作为检测基桩承载力的一种常用试验手段,单桩竖向抗压静载试验在海外岩土工程实践中广泛应用。为了分析该试验的中美标准差异,从主要试验设备、适用范围、试验技术要求和其他差异探讨4个方面,对比了中国标准和美国ASTM标准的差异。对比结果表明:ASTM标准适用范围较广,对试验设备要求更严格。中国标准则对现场试验技术的要求更明确,具有更好的实际操作性。对于加载、卸载、观测时间和终止标准等试验过程,两种标准均作了明确的规定。研究结果可为基桩载荷试验提供参考。
The vertical compressive static load test of single piles is widely used in geotechnical engineering practice overseas as a common test means to evaluate the bearing capacity of foundation pile.The differences between American ASTM standard and Chinese standard were compared from four aspects:main test equipment,application scope,test technical requirements and other differences in order to analyze the difference between Chinese and American standards.The results showed that ASTM standards had a wider scope of application and stricter requirements for testing equipment.Chinese regulations had clearer requirements for on-site testing technology and better practical operability.For the testing process of loading,unloading,observation time and termination criteria,both specifications had clear provisions.The research results can provide a reference for pile load tests in overseas geotechnical engineering practices.
