摘　　要：通过深层搅拌桩作为压桩防护和基坑围护双重作用的工程实例 ,说明该方法在软土地基中能切实有效的保护周围环境 ;同时 ,分析了压桩产生超孔隙水压力对周围环境的影响 ,探讨了"二合一"深层搅拌桩防护作用的工作机理。Through the engineering example on the double effects of cement-soil piles as the protection for the pressed piles and the retaining for foundation pit,it is shown that the method by using cement-soil deep mixing piles is effective to the protection of the surrounding of the site in soft soil.The influence of pore pressure induced by the pressed piles to the surrounding is analyzed,and the mechanism of 'two in one'for the protection effects of cement-soil piles is discussed.
