以天津滨海地区桩基工程实测资料为基础,应用MATLAB软件编制桩基沉降计算程序,分别用等效作用分层总和法和等代实体深基础法计算桩-承台基础沉降,用明德林法计算桩筏基础沉降。分析表明:等效作用分层总和法计算值小于实测值,而实体深基础法和明德林法则基本大于实测值。分析结果可为3种沉降计算方法在天津滨海地区桩基工程中的应用提供参考。
Based on the measured data of pile foundation engineering in Tianjin Binhai area, the calculation program of pile foundation settlement is established by using MATLAB software, and the subsidence of pile-cap pile foundation is calculated by the equivalent action layered sum method and the equivalent foundation deep foundation method respectively. Calculation of Piled Raft Foundation Settlement. The analysis shows that the calculated value of the equivalent action stratified summation method is smaller than the measured value, while the solid deep foundation method and Mindlin’s law are basically larger than the measured values. The results of the analysis can provide references for the application of three kinds of settlement calculation methods in pile foundation engineering in Tianjin coastal area.
