The experimental and analytical studies show that the newly proposed method is accurate in estimating the in-place concrete compressive strength.

Finally, to reduce the analytical error of finite element, with the error estimating method for FEM, the error of new mesh elements are estimated and the elements with large error are refined.
The analytical calculation for one project case shows that the maximal earth counterforces calculated by estimating water and earth pressure together or separately in clay soil were very different.
