| 摘 要： | 由于室内测定的膨胀力结果往往不能真实地反映现场情况,因此,测定膨胀土的原位膨胀力有着极其重要的现实意义.采用加压膨胀法,即利用现场有荷膨胀率试验结果,由内插得到膨胀力值的测试方法,并通过现场试验与室内试验结果的对比,对该方法进行了验证.对比结果表明,该方法能真实地反映膨胀土的膨胀趋势,所测结果能真实地反映现场膨胀力值.且易于操作,有较好地推广应用前景.

| Abstract: | It is very necessery to measure the swelling pressure of expansive soils in-situ,due to the laboratory results can not usually reflect practical situations.Using loading-swelling method ,by use of the results of loaded swelling rate tests,swelling pressure values are obtained through linear interpolation.Field test rusults show that the swelling pressure can reflect the real situations.This testing method may have good applied prospects because of easily to operate. |
