简介：一系列调查被进行学习适用的能力和混合的使硬的深水泥(SDCM)的负担转移机制堆积。实验试验包括六个标本被进行调查在具体核心和thecement土壤之间的摩擦抵抗。二模型堆积和24照原尺寸的堆积被测试检验单个堆积的适用的行为。实验室和模型测试结果显示连贯的力量足够大保证在核心堆积和外部水泥土壤之间的相互作用。full-scaletest结果证明SDCM堆积展出类似的适用的行为到无聊并且cast-in-placeconcrete堆积。一般来说，与合理合成结构，SDCM堆积能有效地播送应用负担，并且由于更生硬的核心的增加，SDCM堆积拥有高适用的能力。基于这些试验性的调查和理论分析的调查结果，一个实际设计方法被开发预言SDCMpile的垂直适用能力。
