Displacement mixing model for safety monitoring of concrete gravity dam

A displacement - mixing monitoring model for concrete gravity dam is set up according to mathematics statistics analytic technique in the paper. The temperature and the time effect factor in the model are extended.Combining the prototype observation data of certain concrete gravity dam in Northeast region, the authors introduce the elementary process setting up the model in detail. The computing results show that the fit precision of the mixing monitoring model is good and it can give play to important effect in the dam safety monitoring.[
