Practices show that the compressive strength , the modulus of elasticity , the permeability coefficient and the compactness of concrete obtained respectively by the compaction method , the unconfined compression static compaction method , the sand trenching and filling method , and nuclear densimeters meet the requirement of design , and the mixing proportion of concrete of the side - wall is reasonable 实践证明施工中用击实法、无侧限抗压静力压实法、挖坑灌砂法及核子密度仪分别检测出的边墙混凝土抗压强度、弹性模量、渗透系数和密实度值均满足设计要求，边墙混凝土配合比合理。
In fact , tamped soil is compacted unsaturated silt . the traditional theory of saturated soil mechanics cannot satisfy the necessity of improved soil research . the theory of unsaturated soil mechanics provides the theoretical evidence for the research of engineering characteristics of the soil 实际上，夯后高饱和度地基土是击实非饱和土，传统的饱和土力学理论已不能满足夯后地基土强度和变形特性的研究要求，非饱和土力学理论的发展为研究高饱和度夯后地基土的工程特性提供了理论依据。
