摘　　要：高压旋喷桩技术以专用设备将水泥浆喷入土层与土体充分混合,形成连续的水泥拌合体,从而达到加固土体、止水防渗的目的。该技术可应用于水运工程中的软基加固、止水帷幕及减小结构后方土压力等。本文以实际工程为例,论述高压旋喷桩在重力式沉箱码头设计中的理论可行性。The technology of high pressure jet grouting pile is defined as follows, cement slurry is sprayed into soil layer by special equipment, and then fully mixed with soil body to form continuous cement block, which reinforces soil body, seals water and prevents seepage. The technology can be applied in soft base reinforcement, water-stop curtain and the reduction of earth pressure behind the structure. The theoretical feasibility of high pressure jet grouting pile applied in the design of gravity caisson berth structure is discussed based on the engineering practice.
