| 摘 要： | 本文通过对比中国标准与美国ASTM标准关于平板载荷试验的规定,总结归纳出两者主要区别在于承压板尺寸和沉降稳定标准,并研究其对试验结果可能产生的影响,提出工程应用中需注意的问题。美国标准通用性较强,具有较大的灵活性,而中国标准相对详细严格。笔者针对博茨瓦纳电厂的平板载荷试验,分别采用中美标准进行试验,试验结果表明:在砂类土等强度较高的地层进行试验,采用中美标准所得到的试验结果相差不明显。本文研究可为我国勘察设计人员进行需采用美标开展平板载荷试验的国外工程提供有价值的参考和解决方案。

| Abstract: | This paper compares the ASTM and Chinese standards about plate loading test. It summarizes their main differences in the following two aspects: plate size and steady standard of settlement. It analyzes that two aspects can bring about effect for test result, and puts forward interrelated attentive issue during project. ASTM standard is more universal and greatly flexible. The Chinese standard is detailed and rigorous. The plate load tests in Botswana power plant are carried out according to US standards and Chinese standard respectively. The test results indicate that the differences between two test results are not obvious for high strength formations(for example sand soil).The results can be used as reference for Chinese surveyors and designers in their overseas projects. |
