Altus AFB Deep Soil Layer Stabilization Test Sections. Volume II. Instrumentation,Construction and Data Collection.

摘要

The basic objective of the research program was to select an airfield with a weak subgrade and to study the strengthening of the subgrade by using different stabilization procedures which included post-hole pile stabilization, drill-hole lime stabilization and lime stabilization by pressure injection. Eleven different full scale test sections were stabilized using the above stabilization techniques while one test section was untreated for a qualitative comparison of the effectiveness of the various stabilization techniques. The test sections were instrumented for measurement of stress and relative displacement. Comparative measurements were taken by loading the various test sections with a load cart which simulated the landing gear of a Boeing 747 aircraft.
