SIGMA/W 抗壓變形分析軟體
SIGMA/W一款用於對岩土結構中的應力和變形進行有限元分素析的專業軟體。它具有全面的本構模型公式，使得這款軟體不但可以對簡單的岩土問題進行分析，也可以對高度複雜的岩土問題，如線性彈塑性、非線性彈塑性、非線性等進行分析，許多經典的土體模型可以使用戶對各種土體或結構材料進行建模分析。
應力和變形分析
SIGMA / W是一種功能強大的有限元軟件產品，用於模擬地球和結構材料中的應力和變形。SIGMA / W分析的範圍可以從簡單的線性彈性模擬到非線性材料模型的土 - 結構相互作用問題。
許多組成土壤模型使您能夠代表各種土壤或結構材料。此外，SIGMA / W可根據外部負載模擬孔隙水壓力的產生和消散。使用SIGMA / W，您幾乎可以分析遇到的任何應力或變形問題。
主要特點
施工順序
GeoStudio的分析樹甚至可以模擬最複雜的構造序列。分析被添加到樹中，形成父子關係，其中每個新分析代表構造序列的一部分。
耦合整合
耦合應力和孔隙水壓力公式可用於模擬建築測序，包括填充放置，挖掘和土壤 - 結構相互作用。
SLOPE / W集成
來自SIGMA / W分析的應力和/或孔隙水壓力可以直接用於SLOPE / W，以進行基於應力的穩定性分析
壓力再分配
應力再分佈分析用於進行強度降低邊坡穩定性分析，模型應力轉移到結構上，例如安裝在失效斜坡內的樁牆，或計算永久變形。
Stress and deformation analysis
SIGMA/W is a powerful finite element software product for modeling stress and deformation in earth and structural materials. SIGMA/W analyses may range from simple linear elastic simulations to soil-structure interaction problems with nonlinear material models.
Many constitutive soil models enable you to represent a wide range of soils or structural materials. In addition, SIGMA/W models pore-water pressure generation and dissipation in response to external loads. With SIGMA/W you can analyze almost any stress or deformation problem you will encounter.
Construction Sequence
GeoStudio's Analysis Tree models even the most complex construction sequences. Analyses are added to the Tree, forming a Parent-Child relationship in which each new analysis represents a part of the construction sequence.
Coupled Consolidation
The coupled stress
and pore-water
pressure
formulation can be
used to model

involving fill

interaction.
SLOPE/W Integration
The stresses and/or pore-water pressures from a SIGMA/W analysis can be used directly in SLOPE/W to do a stress-based stability analysis.
Stress Redistribution
Stress redistribution analysis is used to conduct a strength reduction slope stability analysis, model stress transfer onto structures such as pile walls installed within failed slopes, or calculate permanent deformations.
