Abstract
The study of the impervious concrete wall body stress deformation characteristics of an earth -rockfill dam under different plastic modulus , wall thickness and dam height working conditions gives a reference to design of a similar hydraulic project .Taking the optimized design of the impervious wall reinforcement scheme of the dan-ger-removing and reinforcement project of a certain clay core dam in Zhejiang Province as the basis , the stress de-formation characteristics of the impervious wall were analyzed by means of 2-dimensional nonlinearity .The wall body stress is significantly affected by plastic modulus and dam height and less affected by wall thickness , while its horizontal displacement is significantly affected by dam height and very little by either plastic modulus or wall thick -ness.When a dam impervious wall is designed , importance should be attached to selection of wall body concrete plastic modulus.In general ordinary concrete could be used for the low dams with a height of 20m or less, and the plastic modulus should be controlled to be ess than 5,000 MPa for the 40 –60m high dams.关键词
