旁压仪作为一种现场测试的工具,受到越来越多的重视,关于旁压试验成果的判释理论与方法在国内外也迅速发展起来。用旁压试验可以推求弹性模量E、强度参数c与φ以及初始的原位水平应力pha。确定弹性模量E的方法有几种,基本上都采用弹性理论。但由此确定的E值与从室内试验及载荷 As a tool for on-site testing, the pressure gauge has received more and more attention. The theory and methods of the interpretation of the results of the pressure test have also developed rapidly at home and abroad. The elastic modulus E, the strength parameters c and φ, and the initial in-situ horizontal stress pha can be deduced from the pressure test. There are several ways to determine the elastic modulus E, basically using elastic theory. But the E value determined from this and the test and load from the room
