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。 相似文献

In Australia today, there is still relatively limited use being made of spatial information systems (SIS). Nevertheless, the technology and methodology is developing rapidly. What is already available has the capacity to assist in the process of making social service provision and community planning more people oriented, more effective and more equitable in its outcomes. Recognising the need for a sound social science context, this paper demonstrates, using a range of examples especially geared towards rural and regional Australia, the work of the National Key Centre for Social Applications of Geographical Information Systems. 相似文献
