| Abstract: | In the process of afterward expansion successive beam construction,it is necessary to analyses carefully and control construction machinery,technique parameter to make sure that the elongation value can meet requirement and effective stress is correctly distributed. The author discusses the control of elongation value according to what he learned from experience of construction supervision. |
