This endeavor was specially important specified the Bay Location’s vulnerability to earthquakes—necessitating a Basis capable of withstanding sizeable seismic forces, which was successfully realized through the very careful coordination of template-assisted pile driving.
Inadequate driving program overall performance is often due to insufficient hammering performance or far too-smooth cushioning. The soil could possibly have additional strength, the next damping ratio, or larger soil quakes than in the beginning tested for.
Simply because karst consists of levels of tough rock and tender soil or voids, micropiles might be cased through the delicate zones to knowledgeable rock.
