摘　　要：针对工具式钢管支模架体系的特点,深入分析了单管承载力的理论计算内容,包括工具式钢管容许承载力的计算,以及与Ф48mm×3.5mm钢管立杆的承载力的比较;详细介绍了工具式单根钢管的承载力试验情况;并重点探讨了多杆组合的承载力试验,包括支模架试验方案的确定,对试验结果进行了分析和总结。事实表明,工具式钢管支模架体系具有受力合理、安全可靠、提高工效的特点。Based on the characteristics of tool-style tubular steel formwork-supports, the authors analyze the theoretical calculation of bearing capacity with single tube, including the calculation of allowable bearing capacity for tool-style steel tube, and the comparison with Ф48mm×3.5mm steel tube pole; the authors introduce bearing capacity test of single tool-style steel tube, and discuss bearing capacity test for muhi pole assembly,including the determination of test scheme for formwork-supports,the test results are analyzed and summarized. Facts show that tool-style tubular steel formwork-supports system whose force is reasonable is safe , the work efficiency is improved.
