高压旋喷承重桩的研究

STUDY OF HIGH-PRESSURE ROTARY SPRAYING BEARING PILE

高压旋喷桩作承重桩,设计和施工均无成熟经验,目前国内应用少。从理论分析入手,结合施工实倒,论述高压旋喷承重桩设计与施工的某些特点为,有足够的承载力,保证桩径与桩身强度是设计与施工的关键。

There are no mature experiences in design and construction of high-pressure rotary pile as bearing pile, which is rarely used domestically. This paper, in view of theoretical analysis, with construction example being taken into consideration, expounded some characteristics relating to design and construction of high-pressure rotary spraying bearing pile, i.e. the pile has enough bearing capacity, the key to design and construction is to assure the pile diameter and pile strength..
