复合载体夯扩水泥粉煤灰碎石桩复合地基设计及探讨

DESIGN & DISCUSSION OF COMPSITE FOUNDATION WITH COMPOSITE BEARINGBASE AND CEMENT-FLYASH-GRAVED PILE

在地基处理技术中,将复合载体夯扩桩技术与水泥粉煤灰碎石桩法相结合,取其各自优点,拓展地基处理方法。对二者的原理、方法及组成复合地基的方法进行介绍,并详细介绍了单桩承载力、复合地基承载力特征值及沉降计算。

This paper presents a new technical of ground treatment that adopts the advantage both ram-compaction piles with composite bearing base and cement-flyash-graved pile,the technical develop method of ground treatment. In the paper the author presents the principles and method of design for ram-compaction piles with composite bearing base and cement-flyash-graved pile, and how form composite foundation, and single pile bearing capacity and characteristic value of composite foundation bearing capacity and calculation of settlement are presented detailedly.
