Foundations and beddings
new Combined piled-raft foundation The module enables you to calculate settlement for combined piled-raft (CPR) foundation and parts of load taken by the slab and piles.
The module enables you to compute settlement and moduli of subgrade reaction (subgrade moduli) C1 and C2 under the centre of single footing or foundation slab depending on specified soil properties and load. Settlement is calculated by algorithm of linear elastic half-space or by algorithm of linear elastic layer. SP 50-101-2004, SNIP 2.02.01-83* and updated SP 22.13330.2011 are supported. According to calculated stiffness, the program determines subgrade moduli C1 and C2 by several methods for Fuss-Winkler soil model and for Pasternak soil model as well. Subgrade moduli may be calculated for dynamic loads.
The module enables you to compute settlement and stiffness of a single pile (with account of interaction in pile group) according to SNIP 2.02.03-85 Pile Foundations and MGSN 2.02-01 Beddings, Foundations and Substructures.
Pile under Combined Action of Loads
The module enables you to compute single pile under combined action of vertical, horizontal loads and moment according to SNIP 2.02.03-85 Pile Foundations. The first and the second stages of ‘pile-soil’ stress strain state are considered.
Settlement of Equivalent Footing
The module enables you to compute the settlement of piled foundation from friction piles according to SNIP 2.02.03-85 Pile Foundations.
Principal and Equivalent Stresses in Soil
The module enables you to determine principal and equivalent stresses by different criteria of rupture applied to soil.
The module enables you to check stability of slopes for pits from homogeneous soil by plane and cylindrical slip surface.
Stability of Multi-layer Slope
The module enables you to check stability of multi-layer soil slope by cylindrical slip surface. Swedish method of calculation is applied. Output data is presented as coordinates of landslide surface, landslide pressure, reserve factors for static and dynamic loads. Moreover, total active normal force, active shear force, reactive component of cohesion and radius of sliding surface may be computed.
Bearing Capacity of Piles by Field Test Results
The following building codes are supported: SP 24.13330.2011, SP 50-102-2003, SNIP 2.02.03-85* and DSTU B V.2.1-27:2010.
The module provides the following options for calculation:
- by test field results of driven piles at probe point;
- by results of static probing for screw piles in compression and pull-out loads.
