| 摘 要： | 桩基工程设计，直接影响上部结构的安全及整个工程的造价。通过钻孔挤压分支桩在阜阳商厦三期工程中的应用及试验研究表明，在同一场地、单桩竖向极限承载力相同的条件下，用钻孔挤压分支桩代替钻孔灌注桩，单位体积混凝土的竖向极限承载力标准值可提高１．３１倍，桩基节约投资２７０万元。由此可见，在大柱网、大承载力柱桩基工程中，钻孔挤压分支桩更能充分发挥其优越性。

| Abstract: | The design of the pile foundation dire the safty of the upper structure and the cost of the engineering .Through the application and experiment of the drilling pile with squeezing branch to the 3rd period engineering of The Fuyang Business Building,it indicates that, at the same site and same vertical limit bearing pressure, by use of the drilling pile with squeezing branch to take the place of the poured drilling pile, the criterion of vertical limit pressure for per volume of the concrete will increased by 131%,and it will save 2.7 million yuan.In this awy,the drilling pile with squeezing branch will give the reins to its great superiority in the engineering of large pillar net and large bearing pressure pillar pile. |
