Based on the collected material parameters of the core wall dam in each area of Lianghekou, the \"Nanshui\" model calculation was modified for parameter calibration, and deformation calculation analysis of the filling and water storage process was carried out based on this.\n
The calculation results show that the settlement measurement values of various parts of the core wall axis gradually increase with time, and overall show a general pattern of fast growth in the early stage and slow development in the later stage. The settlement pattern is in line with engineering experience, and the numerical analysis settlement pattern is consistent with actual monitoring, which can better predict the distribution of settlement along the core wall axis in the two river mouth dams.", "ds_ref_way": "", "ds_abstract": "
