Study on Calculational Methods for the Settlement Process of High Filling Canals

Yu, F.; Zhang, Y.; Cheng, S., and Yu, J., 2015. Study on calculational methods for the settlement process of high filling canals.

Variations in the settlement process of high filling canals are difficult to predict. This thesis, by means of the ANSYS finite element, determines the law governing the influence of fill height H, elastic modulus E, and Poisson's ratio μ on the settlement of canals and puts forward the lateral deformation correction factor K₁ and additional settlement correction factor K₂ correcting the modulus of compressibility of the fill in the loading process. On the basis of the layered summation method, we establish a calculation method applicable to the settlement variation process of high filling canals. The method involves fewer calculation parameters and allows for the influence of lateral deformation, additional settlement and modulus of compressibility as the depth varies. It is with this method that the settlement variation process and aggregate settlement of high filling canals from the start of filling until the post-fill steadiness of settlement can be legitimately calculated and worked out.
