有限元技术在碾压混凝土坝应力计算中的应用

介绍了碾压混凝土坝筑坝技术是一种新型筑坝技术，它成功地将混凝土坝结构与土石坝施工方法两者的优越性紧密的结合起来，通过对其结构特性的分析，对层间应力做了系统的研究，建立有限元等效模型，提出求解层间应力的方法，并通过工程实例验证了此方法的实用性。

On application of finite element technique in calculation of stress of roller compacted concrete dam

With an introduction on the principle of GPS high-rise fitting, applying two GPS high-rise fitting methods of plane fitting and polynomial functions fitting, it processes two surveying areas with different terrain and different length, compares the advantage and disadvantage of two methods, and then proposes precautions in choosing GPS leveling joint method.
