| 摘 要： | 采用微孔陶瓷压力探头测土壤水的负压力，是目前工程上常用的一种方法。对测得的负压力和土壤含水率之间的数学关系探讨，目前国内、外还处于空白。根据自行研制的孔隙水压力仪测得的负压力，对应土壤含水率之间的关系，在试验数据、实际监测数据和前人结论的基础上，得出了一种算法。根据该算法编写的软件，目前已应用于长江三峡巫山地区的地质灾害监测中。 |

| Abstract: | It is a common way to monitor pore water pressure using pore water cell on geotechnical project.A new style of pore water cell has been developed by our institute.It is porous ceramic sensor.The data coming from cell may be negative or positive.The positive data is the water level of the saturated soil from the sensor to the surface.If the data is negative,that means the soil is not saturated.But the mathematic relation between the negative pore water pressure and the aquiferous rate of soil hasn't a conclusion internationally.Through studing the data receiving from the cell developed by ourselves and the data of soil acquiferous rate receiving from lab,we conclude an arithmetic on the basis of former achievement.Based on the arithmetic,we program a set of software.The software is used to the monitoring of the Three Gorge's geological disaster and get a better result.The sencond half of the paper introduces the soft's flow chart and how to realize it. |
| Keywords: | micro-porous seramic pore water pressure meter negative water pressure of soil water content of soil arithmetic (aquiferous rate of soil) |
