共振法测定地基承载力及变形模量的一些改进

SOME IMPROVEMENTS ON DETERMINING BEARING CAPACITY AND MODULUS OF SOIL FOUNDATION

本文作者提出了以自由振动代替强迫振动的动载试验方法,用共振法测定复合地基承载力和变形模量,文中介绍了该法的试验步骤和工程实例。为重复利用预制荷载板,本文建议在土表与荷载板之间铺设石膏层。

To determine the bearing capacity and modulus of soil foundation using RPT, the author of this paper proposes a new dynamic testing method with free vibration instead of forced one. In this paper the proce- dure of the method is described and an example is presented in order to use precast concrete loading plate repeatedly, the author also suggestes that a gypsum layer should be laid between the bottom of the plate and the soil surface.
