摘　　要：预制桩打入时的挤土作用会使附近已打好的桩及原有建筑物或周围其他设施产生破坏。挤土程度的大小除了与桩的截面积及某处与桩间的距离有关外,还与桩长、桩型、打桩速率及打桩顺序有较大关系。本文即讨论上述因素对挤土影响的定量关系。The extrusion squeezing caused by the precast piles could damage the existed piles nearby and existed buildings or the other surrounding facilities. The land squeezing extent has much sonething to do with pile length,pile type the pressing speed & the sequence of the piling work as well as of the piles cross section and the distance from some particular points to the piles or between the piles. All thess factors are discussed in this article..
