简介：杰克起来，单位广泛地在在全世界钻工程正在起一个成功的作用，并且他们的安全和效率在研究和工程实践拿越来越多的吸引力。spudcan穿入深度的精确预言在决定杰克起来联合起来是否是可行的在这个地点操作是相当有帮助的。太大的穿入深度的预言可以在随后的抽取过程由于潜在的困难导致犹豫或甚至一个地点的拒绝；一样在操作期间由于可能的不稳定性的问题太小的深度预言是真的。然而，在预兆的结果之间的偏差和最后的地数据通常存在，特别当strong-over-soft土壤在阶层被包括时。最终的决定在很大程度上有时取决于实际经验，不是指南给的预兆的结果。它是有点危险的，但是没有选择。因此，特别在有strong-over-soft土壤侧面的阶层，为spudcan穿入深度的一个可行预兆的方法着急地被需要由杰克起来工业。鉴于这，预言spudcan穿入的方法上的全面调查被执行。为不同土壤侧面的类型，为spudcan穿入深度的预兆的方法被建议，并且相应实验也被进行验证这些方法。另外，验证建议方法的可行性推进，在华南海遇到的一个实际工程盒子是也介绍了，并且相应数字、试验性的结果也被介绍并且讨论。
