【摘要】 离心模拟试验是通过离心机的转动创造超重力场,使小比尺模型处于原型应力状态,从而模拟土工构筑物力学特性的一种研究手段。随着工程技术的不断发展和技术难度的逐渐提高,在超重力场中开展模拟实际工况中的特定动作,逐渐成为离心模拟试验中的一个热点问题,而如何在超重力场中实现大荷载力的施加是离心模型试验研究中的一个难点。为解决这一问题,中国水利水电科学研究院基于液压技术,开发了可在超重力场中模拟各种施工动作的试验系统,本文介绍了该系统的工作原理和主要特点,并结合试验案例,证明该系统的实用与可靠性。更多还原

【Abstract】 The purpose of centrifuge modelling is to produce a physical scaled model to replicate the realprototype system by increasing the gravitational acceleration level and proportionally reducing the dimen-sions. Due to rapid progress of technologies,how to simulate some specified motions in high gravitationalfield becomes a hot topic. How to exert large load force is the most difficult problem to solve in centrifugemodelling researches. IWHR made a hydraulic system that can provide a large power and process specifiedgeotechnical engineering motions in high gravitational field to solve this problem. This paper introduces theprinciples and features of this hydraulic system and proves it valid and reliable through an example.更多还原
