| Abstract: | In light of the specific circumstances and the analysis of observational data of Mianhuatan dam,the safety monitoring index of horizontal displacement at the top of 2#,4#,5# typical dam section is determined by means of confidence interval estimation method,typical small-probability method and structural analysis.A comparison is made on results derived from these methods to give some proposals and measures for improvement. |
