| Abstract: | The forward intersection method is an effective method for checking and staking-out the center of the steel protective canister in the construction of the Sutong-Yangtze-River-Bridge, it is used widely in surveying of steel protective canister. The problem about making use of increased control point is discussed in detail. The necessary accuracy of increased control point, the optimum intersection figure and effective measure for precision position of the steel protective canister are discussed too. Some valuable conclusion is drawn in the paper. |
