Research conclusions: ( 1) To reduce the workload of blasting，the form of short piling can be used in the artificial covering layer at bare rock bed． The depth into rock，that is calculated by using“Lalyqin hypothesis”in the short piling condition，can make sure their safety and reliability; ( 2) Because inability to accurately calculate the artificial covering layer for bridge pile and piles of lateral resistance platform，two constraint ways of hinge end and consolidation at the bottom of pile can be used for calculation． The actual results are between their two results; ( 3) If temporary bridge piles and platform piles can’t meet the safety and reliability requirements in an independent state，the connection between the two systems should be increased． The specifications，quantity and location of the connection system need to be analyzed by the overall analysis of system’s strength and stability．
