摘要
根据＂网~桩~土＂三者协同作用机理,探讨了承载力计算公式中影响桩间土承载力折减系数β取值的各种因素;并由8个工程实例反分析折减系数β值,依据分析结果给出了承载力折减系数β的建议取值1.0~1.2。
According to the interaction among net,pile and soil,various factors influencing the value of bearing capacity reduction coefficient β are discussed.By back-analyses of reduction coefficient β in 8 typical engineering projects,the suggested value of it is 1.0～1.2.
