复合地基承载力载荷试验及承载力确定的标准化问题

Standardization of bearing test and the determination of bearing capacity of composite foundation

根据复合地基现场载荷试验资料,研究了复合地基破坏模式、褥垫层、载荷板宽度等因素对根据复合地基载荷试验评价复合地基承载力的影响,分析了根据单桩复合地基载荷试验、单桩及土载荷试验判定复合地基承载力的差异性。建议应对复合地基载荷试验标准化问题给予足够重视。

Based on the result of bearing tests, the effects of failure pattern of composite foundation, bedding sand and width of loading plate on the determination of bearing capacity of composite foundation have been studied. The studies have demonstrated the difference between the bearing capacity determined by bearing test of composite foundation or by bearing test of soil and pile respectively. The studies show that much attention should be given to the standardization of bearing test of composite foundation.
