一种新型载荷试验的研究

Research of a new type of loading test

针对静载试验要点中三种反力方法的不足,提出了用地锚作为反力的新技术,采用空间组合桁架+地锚组合结构,通过有限元方法研究了地锚的受力状况,提出了计算极限抗拔力的经验公式,从而在一定的荷载范围内解决原有方法的不足。

According to the deficiency of the three kinds of reacting force method in static loading test keys, it puts forward the new technology of taking ground anchor as reacting force, takes the combining structure of space composite truss and ground anchor, makes a research of the force of ground anchor through finite element method, and puts forward the experienced formula of calculating the extreme limit of anti-lifting capacity, so as to solve the deficiency of the original method in a certain load range.
