Based on the load transmission mechanism of space truss, and referenced theanalysis of test materials, a formula for calculating the bearing capacity of reinforcedconcrete compression strut is introduced. By using the theory of plastic hinge-line, anupper limit solution of bent bearing capacity for four-pile cap, which coincidesprecisely with the practical measurements, is obtained. By utilizing the reaction ofthe soil under cap and by basing on the method of plastic ultimate analysis, an upperlimit solution of punching shear bearing capacity for pile cap is acquired, which. coincides precisely with the practical measurements, and the formula is similar to thecode.A brief discuss on cooperative work of strip beam of foundation and single rankof piles is made. Separately considering the pile-cap and the pile-group, thencoupling their matrix of rigidity, the inner force of pile-cap is solved by the numericalmethod under some reasonable supposition. In comparison with other method, thecalculating results are exact, reliable and convenient in using. The method provides apowerful tQol fOr further analysis and research on this kind of structure.

本文以空间桁架传力机理为基础，结合试验资料分析，推导了钢筋混凝土等边三桩承台受冲切承载力计算公式；根据塑性铰线理论，导得了与试验结果吻合良好的四桩承台受弯承载力的上限解；利用承台底土反力分布，根据塑性极限分析方法，导得了桩基承台受冲切承载力的上限解，在此基础上，通过简化假定，得到与规范公式相类似的承台受冲切承载力实用公式，该公式能方便考虑台底土反力作用，与试验结果的吻合程度比规范公式好；简要讨论了桩基条形承台梁与单排桩的协同工作分析；在一些合理假定的基础上，将承台与群桩分开考虑，分别得到其刚度矩阵后进行耦合，通过数值方法求解承台内力，算例表明，该方法结果准确，使用方便，为该类结构的进一步分析研究及工程设计提供了强有力的工具。

Lemon tree 歌词:I'll sitting here in a boring room, It's just another rainy sunday afternoon, I'm wasting my time I got nothing to do, I'm hanging around I'm waiting for you. But nothing ever happens and I wander. I'm driving around in my car, I'd like to change my point of view, I feel so lonely I'm waiting for you, But nothing ever happens and I wander. I wander how I wander why yesterday you told me about blue blue sky; and all that I can see is just a yellow lemmon tree, I'm turning my head up and down I'm turning turning turning turning turning around and all that I can see is just another lemmon tree. see,dalada,diladada... I'm sitting here I miss the power, I'd like to go out taking a shower, but there's a heavy cloud inside my head, I fell so tired put myself into bed, but nothing ever happens and I wander. I solation is not good for me, I solation I want to sit on a lemmon tree . I'm stepping around in adesert of joy, baby anyhow I'll got another toy, and everything will happen and you'll wander. I wander how I wander why ?

中文翻译：一个人孤单单的下午当风吹得每棵树都想跳舞记得昨天你穿蓝色衣服你说对爱太专注容易孤独这句话什么意思我不清楚我爱上了云爱上你多么希望像你自由来去原来星期天容易思念反覆看部电影一遍一遍孤独的流著眼泪回忆太美爱多美丽充满香气只是在心里它总是酸溜溜地我不懂我自己越来越像 Lemon Tree 我一天一天更爱你我不管不管不管爱会苦苦地海蓝蓝的天气我的爱是 Lemon Tree 我爱上了云爱上你多么希望像你自由来去原来星期天容易想念反覆看部电影一遍一遍孤独的流著眼泪回忆太美 Isolation 想住进你心里 Isolation 期待下雨的一棵 Lemon Tree 你总是望著蓝蓝海面说著流浪过的梦容易实现这句话什么意思我不清楚爱多美丽充满香气只是在心里它总是酸溜溜地我不懂我自己越来越像 Lemon Tree 我一天一天更爱你我不管不管不管爱会苦苦地海蓝蓝的天气我的爱是 Lemon Tree 哦。。。。
