This paper adopts different material properties of concrete.
Fig. 3 Geometry model of arch dam and foundation Entire model contains three materials: concrete, low elastic modulus of concrete and rock foundation.
In addition, application of the low elastic modulus of high strength concrete has a certain feasible in theory, but it is difficult to selecting materials, concrete strength test is limited, there are less practical engineering examples.

Swelling and shrinkage due to moisture-change is one of the expansive soil’s characteristics, which is similar to the behavior of most materials under thermal effect.
It is reasonable to assume that the swelling-shrinkage behavior due to moisture-change is similar to the temperature effect on most solid materials which can be analyzed widely and maturely by thermo-mechanics theory.
