灌浆技术在软基处理中的应用

Application of Grouting Technique on the Soft Base Disposal

在灌浆技术的基础上,根据具体工程进一步发展了“树根桩”技术.通过灌浆加固软塑坡积层地基和软硬互层地基的实践,从灌浆特征、施工技术难点及各种参数的确定进行分析,从而说明灌浆技术在软基处理中的作用.

On the basis of grouting technique—— — the grout ing tech nique of stake of tree root like is developed combined with the practice.The applica tion of high-pressure grouting method to strengthen the soft base,soft plastic hillside-deposit layer and the soft-hard alternant stra-tum,is illustrated.The character of grouting,the key factor of construct technique and the determination of different parameter are analyzed.The function of high-pressure grouting tech-nique is demonstrated.
