关于钻孔灌注桩孔底压力注浆计算的几个问题探讨
DISCUSSION OF SEVERAL ISSUES CONCERNING CALCULATION OF BOTTOM PRESSURE GROUTING OF BOREHOLE INJECTION PILE
【摘要】 提出软土地区的钻孔灌注桩孔底压力注浆中的渗透型注浆中三种扩散假设和计算方法及劈裂型注浆理论计算;并对注浆后受注体强度影响因素以及注浆控制、浆液和水灰比选择、注浆顺序和时间、扩散半径等注浆设计问题进行了探讨。
【Abstract】 The paper gave three diffusion hypotheses and calculation method of the penetrative grouting at the bottom of borehole pile as well as theoretical calculation of cleaved grouting,and then discussed the issues as factors affected by the strength of grouting body, grouting control,grout,water-lime ratio options,grouting sequence and time,diffusion radius,etc.
