摘　　要：以水电站软土地基进行注浆成桩项目为例,探讨了高压旋喷压力对土体强度的影响,同时研究了不同旋喷压力下成桩的荷载位移曲线。研究表明,土体的单轴抗压强度随着高压喷射灌浆压力的增加而增加,同时土体抗压强度与抗剪强度之间呈明显的线性相关性,拟合度高达0.99;高压旋喷桩的性能与其喷射压力正相关。Taking the example of grouting pile forming project on soft soil foundation of hydropower station,this paper explores the influence of high-pressure rotary jet pressure on soil strength,and studies the load displacement curve of pile forming under different rotary jet pressures.Research has shown that the uniaxial compressive strength of soil increases with the increase of high-pressure jet grouting pressure,and there is a clear linear correlation between the compressive strength and shear strength of soil,with a fitting degree of up to 0.99.The performance of high-pressure rotary jet grouting piles is positively correlated with their injection pressure.
