摘要
通过现场对预应力管桩底部采用高压旋喷法进行加固这一新的施工工艺试验,探讨预应力管桩桩端为水泥土情况下的受力机理及提高管桩端阻力和单桩极限承载力的效果,并探讨其在天津地区的适用性。
Based on field tests of prestressed concrete pile that bottom soil is consolidated by high pressure rotary jet grouting. The mechanical property of the pipe pile that there is cement soil under the tip and how it effects on the pile tip resistance and single pile ultimate bearing capacity is studied. The applicability of bottom-consolidated pipe pile in Tianiin is discussed.
