Study on Bearing Capacity of Long Short Pile Composite Foundations of High-rise Building under Thick Soft Soil Layer
In order to improve the bearing capacity of high-rise building foundations under thick soft soil layers,a study on the bearing performance of long and short pile composite foundations is proposed.Design long short pile composite foundations based on geological survey results,analyze its bearing behavior and settlement situation;Using the Mohr-Coulomb model,complete the simulation of bearing capacity.The experimental results show that when the single pile bearing load of short and long pile bodies is maximum,the settlement results are both around 5.00 cm.When the floor height of the building is 30.00 m,the average unit load settlement is 0.51 cm.The proposed method can reliably analyze the bearing performance of long short pile composite foundations in high-rise buildings with thick soft soil layers,providing a reliable basis for the design of long short pile composite foundations in high-rise buildings with thick soft soil layers.
