Instructions for preparing the paper for 1 Oth international conference 'modern building materials, structures and techniques' displacement of horizontally loaded piles

摘要

In the article results of bearing capacity of horizontally loaded piles are presented and analyzed. Three groups of piles consisting of 2 or 3 piles have been tested in the construction site of Mariampoles multifunctional sports palace. Opening distance of the building was equal to 83 m. Soil conditions - week, soft soils. Type of piles - vibrated cast-in-place. Method of installation - vibrating the steel pipe into the ground using the vibrator. Length of piles - around 9 meters, diameter - 380 mm. Design vertical load on foundation having 18 piles-Nk = 772,3 kN, design horizontal load on the same foundation - Qk = 1650 kN and Mk = 9805.0 kN * m. In the article horizontal load - horizontal displacement relationships are presented and conclusions on bearing capacity of pile foundation for action of horizontal loads given.
