Ground and Rock Anchors Design Workshop (1.2 CEUs)

Description

Daily Schedule:
8:30am - Session begins
4:30pm - Adjournment
 
Description
Strengthening and stabilizing soil and rock masses, and resisting structural movements are achieved by anchoring via prestressed reinforcement. To withstand lateral forces, temporary tie-backs in soil are also necessary for successful construction of shallow foundations.

Ground and Rock Anchors have vast engineering applications and could be used in many projects either within the new design phase or after construction to strengthen components.
Ground and Rock Anchors are important components of ground support, soil improvements, foundation underpinning, wall support and endless other applications. This course is focused on the design, construction and protection of Ground and Rock Anchors.

Objectives

This practical and informative course would be beneficial for practicing engineers, technicians and technologists interested in safe and economic methods for strengthening engineering structures.

The objective of this course is to provide an in depth review of design, applications and installation methods for anchoring in rock and soil.

After you attend this course you will be able to:

  • Understand the design procedures of ground and rock anchors
  • Perform design for variety of different ground and rock anchors
  • Select the right anchors materials for the right site conditions
Special features

A project design workshop will be conducted under the instructor supervision, please bring in your calculator.
A revision and demonstration of available commercial design software will be introduced.

Target Audience


Practicing engineers, technicians and technologists interested in safe and economic methods for strengthening engineering structures.
This course will be of interest to a wide range of technical personnel who wish to increase their understanding of ground anchors.
  • Consultants
  • Structural engineers
  • Civil engineers
  • College and university faculty
  • Public works and construction department employees of federal, provincial and municipal governments
  • Engineers responsible for large industrial, commercial or institutional facilities who must deal with different types of foundations
The course will be of interest to a wide range of practicing civil engineers at different stages in their careers. Some familiarization with soil mechanics is desirable but the knowledge is not required at a specialist level. The course will be most beneficial to geotechnical engineers, engineering geologists, foundation designers, project engineers, and highway/bridge engineers who are involved in the design and construction of foundations.
