| The surface cracks of concrete dam in the Fengman projects were surveyed and detected with non-damage detection methods in the fields. The pouring process of the concrete was simulated with finite element method, and then the stress distribution in the dam was computed. Based on the survey, detection in the fields and theory researches, the reasons of forming cracks have been completely studied. It is reference valuable for searching the strengthening measures of cracks and feasible scheme of strengthening dam in the cool regions. |
