Use of on-site burial of pore water pressure meter, to pore water pressure dissipation over the situation to determine the number of tamping, tamping the time interval between times.
Research on dissipation of excess pore water pressure in one-dimensional finite strain consolidation of soft clays
The value of pore water pressure dissipation can be divided into two parts. One part is produced by vacuum degree and the other part by groundwater table lowering.
The effect of different cyclic shear stress path under isotropic consolidation on the relationship of pore water pressure and accumulated energy dissipation is very little, itcan be ignored.
The conclusion shows that DJM has more influence on the pore water pressure of the upper soil, and PVD and DJM both have more influence on the lower soil.
Modelling of tide induced pore water flow and solute transport in a salt marsh
The strain excess pore water pressure is a response of the residual strain potential coupled with the skeleton of soil.
The soil samples used in the test are under half-solid state in which the bound water is principal part of pore water.
Based on the analysis and research on test results, it discusses the existence of low water-cut oil layers due to porous media and pore water in micro pores of reservoir.
Field test on pore water pressure induced by PTC pile installation in soft ground
Early diagenesis records and chemical composition abnormalities in pore water for methane-seep in sediments from the southern Qiongdong Basin
The importance to monitor the pore water pressure and to study the permeability of soil under the north anchorage of Jiangyin Yangtze River Highway Bridge is analyzed firstly.
Although an order of magnitude smaller, the pore water pool can supply enough nutrients to build up the macrophyte biomass pool, but only if a fast turnover is attained.
In Changxing Basin, there are abundant ground water resources, such as pore water of Quaternary system, fracture water of sandstone, fracture water and cavern water of carbonatite.
The results also showed that the relationship between the normalized pore water pressure and the generalized strain fit the bilinear model.
Experimental research on the effect of pore water pressure on the creep laws of soft rock
Change of earth pressure, pore water pressure, underground water level, surface deformation, and sub-surface movement all have direct relationship with distance between shield and testing section.
Water filling sources of underground mine in Pingshuo mining area have Quaternary pore water, surface water, Permo-Carboniferous sandstone fissure water and Ordovician limestone karstic fissure water.
It is still deserved to study the liquefaction strength and dynamic pore water pressure and post-liquefaction character of silt when the clay particle content and silt particle content change.
But the negative pore water pressure in the soft soil is smaller, which is decided by the geologic characteristics of the soft soil.
The pore volumes and the amounts of pore water also may vary considerably in actively expelling source beds.
High variability was found in the interstitial water using a1 cm resolution device. Nitrate was never detected in the pore water.
The curve shape of pore water pressure developing under isotropic consolidation is not the same as that under anisotropic consolidations.
