当计入体积力时，与重力式挡墙等厚(B)的悬式挡墙，在开挖深度(D)处的墙体截面内力 Oj)与埋深为零的重力式挡墙基底应力可用同一公式表达，特别在偏士距e<+B时，说明具一定 嵌入深度(H)的粉体喷搅桩(简称粉喷桩)墙兼有上述两种挡墙的受力特性。文中视桩墙为刚体，藉 助于考虑地基弹性抗力的m法和弹性理论公式，提出一种有关粉喷桩墙的实用设计与变位计算方法。

When the body force is put into account，for a cantilever retaining wall with a thickness (B) equal to a gravity retaining wall，both the internal force (a) in the section of the wall body at the excavation depth (D) and the basal stress of a gravity retaining wall with a zero embedment may be expressed with the same formula,especially when the eccentric dis?tance The paper presents that the wall of a dry jet mixing pile (DJMP) with certain embedment (H) has both the mechnical properties of the above retaining walls. It is assumed that the pile wall is a rigid body and the paper puts forward a practical design and calculation method for DJMP by means of atr m,f method which considers the foundation，selastic resis-tance and an elastic theoretical formula.
