浅层就地固化桩土刚性复合地基沉降计算新方法OA北大核心CSTPCD
New Calculation Method of Shallow In-Situ Solidification Technology Combined with Pile-Soil Rigid Composite Foundation
针对就地固化桩土刚性复合地基沉降计算研究的不足及现行规范此类工况沉降计算方法的局限性,首先剖析了就地固化桩土刚性复合地基沉降机理,分析了土拱效应下的桩端应力分担比例和等沉面以上负摩阻区的附加应力对沉降的影响,提出了就地固化桩土刚性复合地基沉降计算的新方法,并通过数值模拟和工程实例进行了验证.验证结果表明,就地浅层固化土技术,可强化土拱效应、增强桩基传递效应,能有效减小复合地基的整体沉降,新沉降计算方法准确可靠.
Considering the shortcomings of settlement calculation research on shallow in-situ solidification combined with pile-soil rigid composite foundation,and the limitation of settlement calculation method in current specifications under similar working conditions,this paper analyzes the settlement mechanism of shallow in-situ solidification combined with pile-soil rigid composite foundation,studies the sharing proportion of pile end stress under the soil a…查看全部>>
