非饱和土有效应力的大气张力公式与新概念土力学

Atmosphere Tension Formula of Effective Stress of Unsaturated Soil and New Concept Soil Mechanics

海南学者蒙理明,在《建材世界》期刊共发表10篇论文,初步建立"非饱和土有效应力的大气张力公式与新概念土力学"的构架。其要点有:应该用有效应力的概念代替经典有效应力原理,即有效应力是土体中提供抗剪强度的点的集合所对应的应力;非饱和土有五相;自由水和孔隙气具有等效压缩刚度(等效压缩模量和等效压缩系数);有效应力的实质是自由水和孔隙气没有抗剪能力;大气张力抗拉强度,揭示了非饱和土的"吸力"之谜;大气张力库仑抗剪强度,展示了经典凝聚力的全貌;应该用绝对压强论述土力学。其公式有:非饱和土有效应力的大气张力公式;大气张力系列的饱和度系数和自由水通道率、有效自重应力、地基承载力、郎肯土压力、库伦土压力、土坡稳定、地基压缩变形和渗流固结等。

Hainan scholar Meng Li-ming published ten papers in the journal of The World of Building Materials.He preliminary build the framework of“atmosphere tension formula of effective stress of unsaturated soil and new concept of soil mechanics”.The points are：should use the concept of effective stress instead of classical principle of effective stress,the effective stress is the stress with a collection of points to provide shear strength in soil;unsaturated soil has five phase;free water and pore gas has the equivalent compression stiffness（the equivalent compression modulus and e-quivalent compression coefficient）;the essence of effective stress is free water and pore gas no shear capacity;atmos-pheric tension tensile strength,reveals the suction of unsaturated soil;atmospheric tension coulomb＆#39;s shear strength, shows the outline of the classic cohesion;should use the absolute pressure on soil mechanics.The formulae are：atmos-phere tension formula of effective stress of unsaturated soil;for atmospheric tension series：saturation coefficient and rate of free water channel,effective gravity stress,bearing capacity of foundation soil,Rankine＆#39;s earth pressure,Coulomb ＆#39;s earth pressure,stability of soil slope,the foundation compressive deformation and seepage consolidation,etc.
