Finally a simple and precise criterion for concrete shaft lining failure is established on the basis of test data.

ased on the researches of model tests of concrete shaftlining under non-homogeneous lateral pressure,the resultS were presented in the current designing that considerable wellbearing capacity was obtained and the tensile stresses were eradicates in the frozen shaftlining.

A finite element program is worked out for the concrete shaftlining under non-homogeneous lateral pressure, it is applied to calculate the concrete shaftlining, the results are presented in the current designing that considerable well bearing capacity is obtained and the tensile stress is eradicated in the frozen shaftlining.

Through analyzing the cause of the crack in concrete-pool-wall in waterplant,I have proposed certain preventive measures and applied them in practice and gained some desirable effect.

The distribution formula of horizontal component force between steel anchor cell and concrete tower wall was deduced then.

Combined with specific engineering,it introduces construction process of artificial pore-forming pouring pile from fabrication of ferroconcrete dado、maintenance and binding reinforcement of mould,and analyzes its benefit,the result indicates that improvement ensure safety & quality and obtain good benefit.
