【摘要】 本文详细分析了国内外现有液压静力压桩机两种液压控制系统的设计原理、设计准则及其实施途径，并从压桩力，压桩速度、能量利用率等方面对代表机型的主要性能进行了理论计算和对比分析，得出了准恒功率设计法更适合于液压静力压桩机液压控制系统的设计研究等结论。更多还原

【Abstract】 Design principle, criteria and way of implementation of two hydraulic control systems on hydraulic static pile presses home and abroad are analyzed in detail in the article. Main performance of typical model is theoretically calculated and comparatively analyzed in the aspects of pile press force and speed and power efficiency. It is concluded that quasi-constant power method is more appropriate to the design of hydraulic control system on hydraulic static pile press.更多还原
