الملخص EN

The flexibility coefficient is popularly used to implement the macroevaluation of shape, safety, and economy for arch dam.

However, the description of flexibility coefficient has not drawn a widely consensus all the time.

Based on a large number of relative instance data, the relationship between influencing factor and flexibility coefficient is analyzed by means of partial least-squares regression.

The partial least-squares regression equation of flexibility coefficient in certain height range between 30 m and 70 m is established.

Regressive precision and equation stability are further investigated.

The analytical model of statistical flexibility coefficient is provided.

The flexibility coefficient criterion is determined preliminarily to evaluate the shape of low- and medium-sized arch dam.

A case study is finally presented to illustrate the potential engineering application.

According to the analysis result of partial least-squares regression, it is shown that there is strong relationship between flexibility coefficient and average thickness of dam, thickness-height ratio of crown cantilever, arc height ratio, and dam height, but the effect of rise-span ratio is little relatively.

The considered factors in the proposed model are more comprehensive, and the applied scope is clearer than that of the traditional calculation methods.

It is more suitable for the analogy analysis in engineering design and the safety evaluation for arch dam.
