摘　　要：对杭州绕城高速公路(北线)进行了路堤荷载下粉喷桩加固软基现场试验研究,以期对软土复合路基的桩土应力比及桩身应力加深认识。Field tests on composite road foundation of soft soil consolidated using mortar sprayed piles under embankment load on loop freeway of Hangzhou were documented. The stress ratios of pile to soil and the stress in pile in the composite road foundation were detailed in this paper.
