Abstract [en]

The construction of Songlin rock-filled concrete gravity dam, located

in the Yunnan province, China began in the end of 2015. In this

master thesis the finite element method (FEM) based software Abaqus

has been used to perform a computational analysis on tension

stresses, compression stresses and sliding stability for static

conditions. One overflow section and one non-overflow section of the

dam have been analysed. The results of the analysis have been

evaluated by comparing with Chinese standards for dam safety and is

intended to help engineers with making decisions in the construction

process of the dam. The measured compressive stress values of both

the overflow and non-overflow section are not evaluated to be within

safe levels, further evaluation is required to ensure the safety of

the dam. The dam is considered to be safe from vertical tension in

the analysed region, however an extended evaluation including the

whole dam base is recommended. The analysed cross-sections for

sliding stability can be considered safe, but further analysis is

required to make a conclusion of the sliding stability of the full

dam base.
