| Abstract: | It introduces a surveying method of high bridge pier's verticality with long span and precision anylysis.Some practical formulas are deduced. This method is simple and the result is credible.Through this method,the higher bridge pier's lean degree can be judged quickly and effectively,and some corresponding measure be taken to ensure the bridge pier's verticality. |
