BURIED SENSORS FOR STIFFNESS MEASUREMENTS OF SOIL USING BENDER ELEMENTS

摘要

A buried sensors for stiffness measurement of soil using bender elements is provided to reduce vibration transferred from a vibration sending member to a vibration receiving member through a pile member by installing resonating pins between horizontal members. A buried sensors for stiffness measurement of soil using bender elements comprises a pile member(10), a pair of horizontal member(20,22), vibration sending and receiving members(30,32), and resonating pins(24). The pile member is installed at the front end of a mandrel and goes into a soft ground vertically. The horizontal members are hinged at upper and lower part of the pile member in parallel to each other. The vibration sending and receiving members are mounted on opposed faces of the horizontal members to send and receive vibration vertically. The resonating pins are mounted on opposed faces of the horizontal members.
