The strengthening effects of reinforced concrete liner cover for tunnel lining with crackles are investigated,and the numerical simulations for two computations of Tieshan Tunnel and Dayakou Tunnel are carried out by using a 2D FEM code.

Because concrete crack will badly affect the security of concrete penstock in hydropower station, the paper applied the theory of BP network and global optimization method to predict the maximum concrete crack width in steel-lined reinforced concrete penstock and brought forward the predicting model on the base of the theory of ANN.

Because concrete crack will greatly affect the security of concrete penstock in hydropower station,the paper applies the theory of global optimization method to predict the maximum concrete crack width in steel-lined reinforced concrete penstock and bring forward a predicting model based on the theory of artificial neural network(ANN).

Nonlinear finite element analysis of reinforced concrete lining of hydraulic tunnels;

There are two lining structure types which are frequently used in engineering presently,one is the reinforced concrete lining,another is the steel lining encircled by concrete.

The cracks of the reinforced concrete lining of tunnel is caused by thermal stress.

Study on large scale water conveyance tunnel structure with shielding segment steel reinforced concrete inner lining

A hydropower station plans to use Penstock Laid on Downstream Surface of Dam,in order to achieve the security,the construction convenience and the economical goal,This article carries on the comparison to the exposed penstock and steel lined reinforced concrete penstock.

The integral model of steel lined reinforced concrete penstock was analyzed by nonlinear 3-D finite element method, focusing on stress of steel lining and reinforcing steel bar, cracking status of concrete.
