Comprehensive material studies were performed in the course of preparation for and implementation of the project, and guidelines for evaluation, design and construction were established on the basis of those studies.
The thermal insulation of a construction is established by the resistances of the materials employed and the thermal surface resistances, which may vary significantly from one building to another because of its location and climatic conditions.
Because the loading conditions of the tunnel during different construction phases vary greatly, a numerical model with three loading phases corresponding to different construction phases was established.
To avoid big deformation, a construction principle was established for the tunneling including the following: (1) Effort should be made to provide confinement pressure to the rock.
A construction principle was established based on a concept of mainly maintaining the rock strength/stiffness and keeping the rock dry, by providing a confinement pressure to the rock, reducing the rock exposure time, keeping water out of the tunnel, etc.
Through carefully examining the site observation and laboratory test results, a construction principle was established for the tunneling on the basic concept of maintaining the rock strength/stiffness and keeping the rock dry, by providing confinement pressure to the rock, reducing the rock exposure time, keeping water out of the tunnel, etc.
The hierarchy of logical-gtrammatical constructions complexity was established.
In order to facilitate further the use of the system, a technique for cell-free construction of recombinants was established using rolling circle amplification and biolistic inoculation of DNA B-transgenic plants.
In 1911, the Coleman DuPont Road, Inc. was established and construction on the highway began.
