Based on the experimental results,characteristics of strain changing,void ratio changing,settlement rate changing against time,and the relationship between stress and strain of MSW were studied.

Meanwhile, effects of the retention time on the relative resistance, compressible coefficient and settlement rate have also studied.

To study the computation method for the settlement rate of saturated soft clay foundations,on the basis of the approximate relation of stress-strain consolidation degree of saturated soft clay,a formula for calculating the settlement rate of foundations is derived and the computation method for the settlement rate of saturated soft clay foundations are provided.

One-dimensional tectonic subsidence histories of 30 presumed wells were calculated,8 wells of which were appraised for their tectonic and total subsidence rates.

According to the well logging data of south Songliao basin,on the basis of formation denude,the authors evolved the research on deposition rate,subsidence rate and buried history.

Observations and analysis of floc size and floc settling velocity at coastal salt marsh in Luoyuan Bay in Fujian Province,China

Takács function was adopted for describing the settling at low concentration and the zone settling, and a compression settling velocity function for the compression settling.

While the settling velocity of animal cells plays an important role in the design of the cell retention device and the estimation of settling operation, the measurement of this critical parameter suffers from the lack of simple and accurate method for a long time.

In connection with impact compaction technology of soil&stone cushion of third airstrip of Pudong airport,it selects such experiment research as constructive technology&quality control,puts forward such constructive control parameters as pressing subsidence ratio(single subsidence ratio),pressing times,pseudo thickness and so on.
