1、基础工程作业专业：岩土工程姓名：何磊学号：12011015计算工具Excel一、题目承受集中荷载的条形基础的抗弯刚度E山=2X12kN.m2,梁长/=10m,底面宽度b=2m,地基土的弹性模量^=20MPa，泊松比卩=0.3。试按链杆法计算梁的挠度、弯矩、地基反力分布曲线，要求：(1)为保证较为准确地给出挠度、弯矩、地基反力的分布形式，要求计算截面不少于11个。(2)建议编程或借助于Excel、Matlab等计算。提交的文木中应给出详细计算过程。(3)独立完成，只勿抄袭，否则该作业成绩为0。F=10

2、00kN5m计算过程2.1选择基本体系如图1所示，取16根链杆，链杆间距l=0.625m(两端第一根链杆距梁端0.3125m),各链杆距固定端依次为给、a2……a】6,其内力为X】、x2……x20o在固定端处冇转角％和位移So。那么，共有18个未知量，如图1所示。图12.2系数计算2.2.15j计算ViJ=/3ba§勺）a＞幻）aj0.30.91.52.12.83.4•1.01.65.35.96.57.17.8&49.09.6ai12537562587512537562587512537562587
