按照土力学理论,饱和土体的压密,是孔隙水压力的消散所造成。在饱和土体上建造建筑物,会产生超孔隙水压力。量测施工过程中的孔隙水压力值,可作为控制施工速率的参数,估算土层的固结度,推算土层最终沉降量,并与理论计算相互验证,为多快好省地完成水利工程和基建项目服务。许多单位都对野外孔隙水压力量测仪器进行过研制,但由于“四人帮”的破坏,使这项研制工作长期处于谁家急需谁家研制,既不定型又不推广,工程结束仪器丢抛的状态,严重地影响了野外孔隙水压力量测仪器的发展。
According to the theory of soil mechanics, the saturation of saturated soil is caused by the dissipation of pore water pressure. Building a structure on a saturated soil produces excess pore water pressure. Measuring the pore water pressure during construction can be used as a parameter to control the construction rate, estimating the degree of consolidation of the soil layer, estimating the final settlement of the soil layer, and verifying each other with the theoretical calculation to complete the water conservancy project And infrastructure project services. Many units have conducted research on the field pore-water pressure measuring instruments. However, due to the destruction of the “gang of four,” this research and development work has long been subject to the development of who needs it urgently, neither stereotype nor promotion. Threw the status of a serious impact on the field of pore water pressure measuring instruments development.
