［摘要］在假設樁體和樁周土體均服從莫爾\|庫侖強度準則的前提下，采用FLAC-3D軟件來研究釘形水泥土攪拌樁在樁頂荷載作用下樁身荷載的傳遞規(guī)律，并對其特征參數(shù)進行分析。結(jié)果表明：釘形水泥土攪拌樁樁身內(nèi)力分三階段衰減；單樁設計參數(shù)對其特征參數(shù)影響較大。在工程設計中應選擇合理的單樁設計參數(shù)，使其特征參數(shù)控制在理想范圍內(nèi)。
［關鍵詞］釘形水泥土攪拌樁; FLAC-3D; 荷載傳遞規(guī)律; 設計參數(shù); 特征參數(shù)

Abstract: On the assumption that pile and its around soil are submit to Mohr-Coulomb strength criterion, FLAC-3D software was used to study the load transmission law of T-shaped cement-soil mixing pile under pile top loads. In the meantime, characteristic parameter of the pile was analyzed. Results show that internal force of T-shaped cement-soil mixing pile suffers from attenuation in three phases, and design parameters of single pile remarkably influence on its characteristic parameter. In order to control its characteristic parameter in reasonable interval, proper design parameters of single pile should be chosen in the design of the project.
Keywords: T-shaped cement-soil mixing pile; FLAC-3D; load transmission law; design parameter; characteristic parameter
