Abstract: According to the actual situation for the varied working conditions and varied variabler of the solf-elevating substructure,we make a separation of the design variable and optimated design by st ges.By means of drawing up a computer program and a ealculating example,we reach a major conclusion which has an important reference value for do sign of self-elevating substructure.
