It was driven through variable soft ground conditions by an earth pressure balanced tunnel boring machine (TBM). The project also includes six drop shafts, three adits to connect offset drop shafts to the main tunnel, and five diversion and odor control facilities.

SEISMIC INSTRUMENTATION OF CALDECOTT TUNNEL The work reported herein was a task in the program to measure the response of tunnels to earthquakes. The objective was to install digital recording strongmotion instrumentation at the Caldecott Tunnel in Oakland, southlakes-cottages.com: J T Ragsdale, R D McJunkin.

Title: Nueva Legislacioun De Amparo Reformada Author: southlakes-cottages.com The Hayward Fault is located just about a mile southwest of the Caldecott Tunnel's west portal. Although no active faults bisect the Caldecott, and tunnels in general tend to resist deformation when there is strong ground motion, the possibility of a large earthquake had to be taken into account in the design and construction of the Fourth Bore.

Feb 11,  · Furthermore, the following topics are included: installing seismic stations, networks, and arrays - working with portable instruments - calibrating instruments - dealing with response information - and teaching about seismic instruments.

This book is primarily intended for seismologists and technicians working with seismological instruments. Dec 19,  · This section focuses on the seismic analysis and design of large linear underground structures commonly used for metro structures, highway tunnels, and large water/sewage transportation ducts in urban areas and can be grouped into three broad categories: (1) bored or mined tunnels, (2) cut-and-cover tunnels, and (3) immersed tunnels (Fig.

The Caldecott Tunnel is an east–west highway tunnel through the Berkeley Hills between Oakland and Orinda, California. Its four bores carry California State Route Named after Thomas E. Caldecott, former mayor of Berkeley, it opened in as a two-bore tunnel. The third bore opened in and the fourth bore in Currently, the two oldest bores carry eastbound traffic and the two newest bores Coordinates: 37°51′17″N °13′00″W / °N.

This paper presents a brief summary of seismic analyses for Caldecott Tunnel Improvement Project. It includes seismic hazard analysis, wave scattering analyses to evaluate soil structure interaction (SSI) for the proposed 4 th bore, and development of seismic coefficient for slope stability design.

Probabilistic Seismic Hazard Analysis (PSHA) was used to establish the rock motion criteria; 1,year and. The book essentially consist of seven divisions: 1. Basic physics 2. Geophones and instrumentation 3. Seismic field design 4.

Rocks, rock physics and well logs 5. The seismic method 6. Seismic interpretation and geology 7. Probability, statistics and mapping Many geoscientists believe that formalism aids in the understanding of the subject.

The Bay Tunnel is a major water supply facility to be constructed between the San Andreas Fault and the Hay ward Fault in the San Francisco Bay Area. The design earthquake for the Bay Tunnel has a return period of 1, years and a horizontal peak ground acceleration of approximately g. An analytical approach is presented for dealing with the seismic design and analysis of both bored (circular) and cut-and-cover (rectangular) tunnels.

This approach considers the soil-structure interaction effect and focuses on the ovaling~racking deformation aspect of the tunnel structures. The procedure. case of the Wrights tunnel for instance, the fault offset at the depth of the tunnel indicates that some of the observed surface ruptures reflect only secondary ground instability effects accompanying the main fault rupture and are not directly related to seismic faulting at depth; a conclusion already obtained for other causes on the.

BART carries abouttravelers every day; and during the peak of the commute across the San Francisco Bay, BART carries as many travelers as the San Francisco-Oakland Bay Bridge. The BART system represents a public investment currently valued at nearly $15 billion, with immeasurable importance to the local and regional economy.

Then the book introduces basic elements of seismic hazard analysis and presents the concept of a seismic hazard map for use in seismic design. Subsequent chapters cover key aspects of the response analysis of simple systems and building struc­tures to earthquake ground motions, design spectrum, the adoption of seismic analysis procedures in.
