贯入桩 meaning in English

penetration pile

The soil plug has an important effect on the pile driveability , and the pile diameter has an important effect on the property of soil plug , too . then the plugged effect judging method and nonlinear model of soil plug of the large ( super large ) diameter , super length , deep penetration pile have been established . hyperbolic model of soil plug was also proposed to calculate the inside static resistance
3 .土塞对大直径、超长桩的可打入性有重要影响，而桩径大小直接影响土塞特性，本文建立了大直径（超大直径）、超长、深贯入桩土塞闭塞效应判断方法和土塞非线性双曲线计算分析模型，并提出了“内侧极限摩阻力动态分布”模式。
Based on the data of pile driving records of a great number of piles in offshore platforms and the project about driveability analysis of super large diameter , super length , deep penetration pile of one oil - gas field in our south sea ， simultaneously , following up the front of the research of pile driving , studies have been performed as followings : 1
本文紧密结合大量工程实测数据和我国南海某大型油气田开发所提出的平台超大直径、超长、深贯入桩基的动力打桩可打入性和承载力的高精度预测分析研究课题，同时跟踪本学科前沿领域，对以下几个方面进行了较为深入的探讨和研究。
