TESTING UNDER WAY ON 'SEISMIC' PILES

The California Department of Transportation is testing deep piles for use under bridges founded on soft soil. The piles being tested can withstand 900,000 lb in compression as well as 700,000 lb in tension. These increased pile capacities will permit Caltrans to retrofit its freeways without resorting to unusually deep piles or too large pile caps that might extend into existing traffic lanes. From an analytical standpoint, these pile tests may lead to better methods for modeling structures on 'soil springs' rather than unrealistic rigid supports. The testing is expected to cost more than $2 million, and help build earthquake resistant freeways in California and elsewhere.
