安徽省电力设计院在全面研究了燃煤电厂废渣的工程特性和桩基础的受力特点的基础上,提出了以钢筋砼为芯,在桩外填充废渣,旨在提高土侧压力系数和桩土摩擦系数并增大端部阻力的新型桩,简称渣壁砼芯桩。试验表明,在软塑-可塑的亚粘土地基中,用两组沉管渣壁砼芯桩与复打桩比较,在承载力分别提高33%和20%的情况下,沉
After comprehensively studying the engineering characteristics of the coal slag waste and the force characteristics of the pile foundation, the Anhui Electric Power Design Institute proposed the use of reinforced concrete as the core to fill the outside of the pile with waste residue in order to improve the lateral pressure coefficient and pile. New types of soil friction coefficient and increase the end of the new type of pile, referred to as slag wall core pile. The tests show that in the soft plastic-plasticized sub-clay foundation, two sets of immersed tube slag wall cored piles are compared with the piling piles. Under the condition that the bearing capacity is increased by 33% and 20%, respectively,
