Course Title: Wisconsin Soil Mechanics, Bearing Capacity and Slope Stabilization

Delivery Method: Live Online

Course Description: This course examines soil investigation and classification, hydraulic and mechanical properties of soils, determining and increasing bearing capacity, and determining and increasing slope stability. Numerous examples will be shared of soil conditions and design practices specific to Wisconsin.

Learning Objectives:

Learning Objective 1:
Learners will be able to describe the need to understand the properties of soil on particular development projects and the value of conducting soil investigations to determine the appropriate type and design of that foundation, which will ensure its longevity and safety.

Learning Objective 2:
Learners will be able to articulate the need to understand the hydraulic and mechanical properties of site soils so that soil compressibility and drainage can be considered for foundation design.

Learning Objective 3:
Learners will be able to calculate soil bearing capacities for shallow foundations, piers and piles, and they will be able to explain how to increase bearing capacity through draining, compaction, and soil improvement.

Learning Objective 4:
Learners will be able to differentiate the stability of natural and engineered slopes, explain why slopes fail, and describe how to use retaining structures to avoid slope failure and landslides.

LUs: 6.5                                                                                              LU Type: LU|HSWs.

Prerequisites: Familiarity with site development and earthwork

Advance Preparation: None

Program Level: Intermediate

Course Expiration Date: 01/31/2025
