【Abstract】 Cement-Flyash Gravel pile the composite foundation technique is the a kind of ground management technique, which is having much higher economic benefits. Through the characteristic, design to the composite foundation to the Cement-Flyash Gravel pile the important point, construction the craft’s analysis, and combining with the characteristics of the north area of Zhangji Coal Mine where is the Choosing Coal Factory, its product storehouse and primeval coal storehouse with engineering work period requesting tightly, investing requesting lower. To use the Cement-Flyash Gravel pile to the composite foundation technique is a very good way to proceed the foundation to handle. After the construction, the result after the examination to calculate is that the economic result of this technique is obvious, the engineering investment saves, identical caliber compare ratio adoption drill a hole to impregnate the stake investment to save roughly 29.4%, the construction speed is quick, and have no noise and the problem of mud pollution.更多还原
