The pile groups efficiency is larger than 1 in the condition of the test. The coaction of pile-soil-cap should be considered in optimum design of pile foundation.
认为类似该场地条件下群桩效率系数大于1，在实际的工程桩基设计中应考虑共同工作以优化设计。

According to the evaluation mode of limit bearing capacity of compound piling, a limit state equation of reliability for the interaction of associated piling, piling cap, and groundwork soil is setup.
根据复合桩基极限承载力计算模式，建立了考虑桩基-承台-地基土三者共同相互作用的可靠度极限状态方程。

The other soil contrast root volume greater than the smallest and biggest phosphorus treatment, the root cap is bigger than too.
