针对软土地基的特殊工程地质条件,探讨了旋喷桩处理软土地基的施工工艺及技术措施。进行了水泥土试块抗压强度试验,成桩后通过钻芯抗压和载荷试验进行检测,结果表明:经旋喷桩处理过的软土地基,提高了复合地基的承载力特征值,提高了土体的抗剪强度,满足了边坡整体稳定性的要求。
Aiming at the special engineering geological conditions of soft soil foundation, the construction technology and technical measures for treating soft clay foundation with jet grouting pile are discussed. The compressive strength test of cement soil test block was carried out. After being piled up, the core compression test and load test were carried out. The results show that the characteristic of bearing capacity of composite foundation is improved by soft soil foundation treated by rotary jetting pile The soil shear strength, to meet the overall stability of the slope requirements.
