This document contains details of the SCM deformable soil model implemented in Chrono. The soft soil model discussed herein is an extended version of the classical SCM Soil Contact Model used at DLR for predicting rover mobility. The model, which is based on a fast semi-empirical expeditious approach that requires few parameters, is ideal for scenarios that require a fast (near real-time) simul...

Many traumatic upper body injuries to deminers are caused by debris generated by anti-personnel (AP) blast mines. This study better characterizes the soil ejecta threat from buried anti-personnel mines and provides an improved evaluation of light upper body protection systems by relating the threat to resultant damage to soft tissue simulants. For each tested soil type, ejecta characterization ...

When a jack-up installed at a clay location and then leaves; it can create several meter deep footprints. In case of soft clay, the spudcan may have actually penetrated much deeper than the observed footprints. When the penetrated spudcan is pulled out, much of the soft remolded clay will flow around it and go back into the hole. This event, leaving a deep region of disturbed soil. The disturbe...

Use of soft clay soils in construction activities has faced many problems. Some improvement, stabilization, and reinforcement methods is required to use these soils in body of roads, sub-foundations and embankments. In this research, the effect of chitin nanofiber and rice husk ash as additives on the behavioral properties and bearing resistance of soft clay soils by considering the processing ...

A numerical model was developed to simulate the response of two instrumented, centrifuge model tests on soft clay and to investigate the factors that affect the seismic ground response. The centrifuge tests simulated the behavior of a rectangular building on 30 m uniform and layered soft soils. Each test model was subjected to several earthquakelike shaking events at a centrifugal acceleration ...

in soft soil areas, equal-length piles are often adopted in the retaining system. a decrease in the bending moment value borne by the retaining structure along the pile depth (below the excavation bottom), leads to an inadequate use of the pile bending capacity near the pile bottom. this paper presents retaining systems with long and short pile combinations, in which the long piles ensure integ...
