欠固结土

当地下水位上升时，常会造成地基土及垫层的软化，强度降低，欠固结土的湿陷；

The rising of groundwater often makes foundation soil and cushion soften , strength fall or underconsolidated soil collapse .

原状欠固结土的力学特性试验研究

Testing Study on mechanical characteristics of natural underconsolidated soils

吹填土地基作为欠固结土，其真空预压加固过程比较复杂，初始条件和边界条件也比较复杂。

The reclaimed soil foundation is consolidated , and its vacuum preloading consolidation process is very complex , so are the boundary and initial conditions .

对于原状欠固结土，体应变对土体结构性的破坏要大于剪应变。

The structure damage of the natural underconsolidated soils caused by the increment of volumetric strain is more significant than that caused by the increment of shearing strain .

新构造运动、全球海平面上升、欠固结土自然沉降以及地面荷载是地面沉降的次要影响因素。

While other factors , such as Cenozoic tectonic movement , rising elevation of the sea water , natural compaction of the unconsolidated soil and ground-loadings also play an important role .

对海相沉积的欠固结土中水平平行顶管施工引起的地面变形规律进行分析，提出地面横向和纵向扰动区范围及工后沉降的计算方法。

The disturbance scopes in lateral and vertical directions , and calculational formulas for ground settlement are gained by analyzing the rules for ground deformation induced by level parallel pipe jacking construction in one underconsolidation soil .

通常情况下，桩基的侧壁阻力主要以正摩阻力为主，当桩周存在一定厚度欠固结土等情况下，桩侧阻力则会出现对桩基承载力不利影响的负摩阻力。

Under normal circumstances , the side friction is dominated . When the pile there is a certain thickness of soil due to consolidation of such cases , the pile side resistance occurs adverse effects on the pile bearing capacity of the negative friction .

欠固结软土路基的设计思考

Considerations of Underconsolidated Soft Soil Roadbed in Design

我国沿海地区，广泛分布着性质极为软弱的近代沉积的欠固结软土。

The unconsolidated marine soft soil has very weak engineering geological properties which is widely distributed in the coast area of China .
