通过大吨位锚固区混凝土模型试验及 ＳＡＰ９１有限元计算分析，论证了锚固区混凝土的抗裂性及极限承载能力，分析了锚下裂纹对承载能力的影响，提出了探索性的建议。并简要介绍了ＳＴＭ 理论，得到了一些经验性的认识
Through the concrete model test of large tonnage anchorage zone and the finite element analysis of SAP91, the crack resistance and ultimate bearing capacity of concrete in anchorage zone are demonstrated. The influence of cracks under anchor on bearing capacity is analyzed and exploratory suggestions are put forward. And briefly introduced STM theory, got some empirical understanding
