AEG BWH Christmas Dinner Party Dec. 18, 2014

Geologists and students:

I want to personally invite you, your spouse, your friend, and your colleagues to the December 18th, 2014 AEG-BWH Christmas dinner party. We will hear a bang-up talk about rockfall protection for our PDH’s, AND get AEG Gear, sparkly rocks, minerals and gems as party favors and during our annual holiday gift drawing. Come in the combined geology and holiday themed sweater that you cannot wear anyplace else! As additional enticement, note that there is a special Couples Discount (only $60 per couple). The meeting is at Brewer’s Alley in Frederick. Please register immediately via email to Patrick Hastings by Monday, December 15, 2014 at AEGBWHSecretary. Below is the full notice.

Chairman, AEG-BWH

Notice of Meeting

Announcement from the BWH Section of the
Association of Environmental & Engineering Geologists

SECTION MEETING
Baltimore MD – Washington DC – Harrisburg PA

TOPIC: Design Guidelines for Rockfall Fences

ABSTRACT:
The design of rockfall protection interventions is part of the rock mechanics science which needs to be addressed from a geologic and engineering approach. The fact to combine the design with an uncertain and unknown space as the rock mass requires a meticulous statistic analysis. The purpose of this paper is to propose a design guideline for rockfall fences, which will take under consideration the uncertainties of the collected data from the project site. A design begins with site investigations to define morphology, geology and geometry of the slope. A good cooperation between geologists and engineers is the base for the successful project. Once the information is obtained, a statistical parametric analysis on trajectories, velocities, bounds height and energies will be carried out. This analysis will allow the designer to adopt the appropriate rockfall solution in accordance with the safety coefficient applied to the uncertainties. The design can be based on the Service Energy Level (SEL) or Maximum Energy Level (MEL), depending on the frequency of events probability, installation and maintenance cost. The adoption of Rockfall Fence Kit designed in accordance with full scale crash tests (ETAG 027) is recommended in order to provide the values of loads and deformations acting through the fence. The location for the installation of the fence needs to take into account also the practicality of the site, in order to create a safe work environment for the installers. Both the design and on-site assistance by the manufacturer is always recommended for achieving the best final results, which is the safety of the people.

PRESENTER:
Ghislain Brunet has been working in the field of erosion control and rock slope stabilization for more than 25 years. He has implemented and organized the sales and the manufacturing of the rockfall mitigation products in the USA for Maccaferri. He has an MBA and a degree in engineering. He is a chairman on the ASTM International Committee for the Geohazard Protection Systems. He has been involved in developing ASTM standards for more than 15 years. He is vice-president and one of the founding members of the Association of Geohazard Professional.

Here is the Google Map link to Brewers Alley. (or here:
https://maps.google.com/?daddr=124+North+Market+Street,+Frederick,+MD+21701,+USA&pw=0&t=h&z=16
); Parking is either where you can find it on the street, OR, there is a
multistory, municipal parking garage directly behind the restaurant (note
the long rectangular building east of Brewers Alley when you open the Google
Map/Satellite link). The clearance is approximately 6”8”, which is lower
than some vans.

The parking garage entrance is off Church Street, a one-way heading east. If
coming north on 355/N. Market Street (from I-270), cross over Patrick Street
(the divider between N & S street designations), and turn Right on Church,
and left into the garage. If exiting I-70 (from Balto, for ex), go north
on North on S. East Street, cross over canal, turn left on E. Patrick, Right
on Frederick and Right on Church into garage on left.

COST (dinner & mtg):
Bring personal or company check or cash to the meeting and pay treasurer
before presentation.
Couples $60
Members: $35
Non-members: $40
Students: $25

MEETING SCHEDULE:
