Through the discussion of the improvement mechanism shaft friction resistances,the bearing capacity of pile can be improved greatly by base-grouting,especially the change of shaft friction can evidently increase vertical bearing limit shaft friction.
同时,基于压浆液对桩底上抬作用的理论研究,推导出桩顶上抬位移与上抬力关系的解析式,并对桩底后压浆桩的极限承载力计算提出建议性修正,可为相关领域的工程研究人员提供一定的借鉴。
补充资料:电泳注浆成型
分子式:
CAS号:
性质:陶瓷浆料的成型方法之一。利用浆料中颗粒荷负电,在直流电场作用下向阳极运动而沉积在模型(阳极)上形成坯体的成型方法。此法可加快坯体形成速度,坯体较致密,可用于面砖,基板等的成型,但有时会因水的电解作用产生气泡,电场不均匀会造成坯体厚薄不均或脱模困难,故尚未得到广泛使用。
