摘　　要：介绍了沿海某化工码头围堰的工程概况及水文气象和工程地质条件,论述了该码头围堰工程高压喷射灌浆生产性试验的工艺流程。通过不同的灌浆参数进行试验,论证围堰堰体及该基础采用高压喷射灌浆防渗的可行性,同时获得高压喷射灌浆的有效扩散范围、施工参数,为防渗设计时选取经济合理的防渗墙孔距及切实可行的施工工艺提供依据。An introduction was made on the general situation, hydrological, meteorological and engineering geologi-cal conditions of the cofferdam works of a coastal chemical wharf. The author discussed the technical program of pro-ductive test which was conducted under various grouting parameters to check the feasibility of adopting high pres-sure jet grouting at the cofferdam body and foundation, obtain the effective diffusion range and construction parame-ters, provide basis for the selection of economical and rational anti-seepage wall hole distance and practical con-struction technique.
