lateral confinement

Authors made some tests including standard penetration on cement-soil piles, drilling for core and in-door compression without lateral confinement to accurately evaluate the construction quality of these cement-soil agitation piles.

通过对桩身水泥土进行标准贯入、钻孔取芯及芯样室内无侧限抗压试验，正确评价水泥土搅拌桩的施工质量。

New formulae for effective confinement area and lateral confinement pressure are proposed.

提出了新的有效约束面积模型及侧向约束压力计算公式。

However, local buckling is more likely to occur for thin-walled tubes, and thus decreases the lateral confinement on the concrete core.

但薄壁钢管在荷载较大时易发生局部屈曲，且降低对混凝土的约束。

Damage model for compression fatigue loading of concrete with uniaxial lateral confinement

定侧压混凝土双压疲劳损伤模型

For the same lateral confinement, high strength concrete columns develop lower strength enhancement than normal strength concrete columns.

在相同的侧向约束下，高强混凝土柱的核心强度提高幅度低于普通混凝土柱。

Second, according to the parameters based on the common tri-axial compression and lateral confinement compression test on the undisturbed soil sample, this paper calculate the soil stress between piles and dry density on the use of FORTRAN program, thus make some important conclusions.

其次，采用原状土样进行室内常规三轴试验及侧限压缩试验，确定试验参数，代入前述理论公式，借助FORTRAN语言计算桩间土土体应力及其干密度，得出了一些结论；
