After 3-day jack-up constructiont,he inclination ratio of building is steady at 0.53‰ and settlement rate is less than 0.007 7 mm per day and tends to be stable.

To analyse of soil body stability in highway embankment with mutation theory,to calculate observation data of settlement,it's consistent with survey and result that provides theory bases for improving control settlement rate.

The dynamic behavior of Logistic growth model is controlled by parameter a, namely transient settlement rate. When parameter a is in the interval [0, 2], the final settlement predicted by Logistic growth model is stable.

1. The mechanism of PCC pile composite foundation, the effects of pile spacing on the settlement rate of composite foundation, the load bearing ratios of pile and soil, and the effective improving depth of composite foundation are analyzed through a field study which monitors the behavior of composite foundation with changeable pile spacing.

Three-point method’s,settlement rate method’s and Hushino method’s predicting precisions are higher,and the calculation starting point and time span do not have much relation,but require special treatment to the original observation data,the calculation is more complex.

4. The research on rolling settlement、 settlement rate and flexure index were made from field tests of rock embankment to study deeply rolling machines、 rolling method、 quality control criteria、 field rolling criteria and the feasibility of monitoring method and the control method of construction technology was discussed.

The final biodegradation settlement rate is determined by the content of biodegradable organic carbon and a dimensionless parameter, which is the product of biodegradation rate and filling time.

Considering the randomness and fuzziness of the failure of piles,the settlement rate of piles is taken as a fuzzy random variable by using related theory of fuzzy mathematics. The membership function is determined by fuzzy statistical analysis of 42 static load tests of prestressed concrete pipe piles in Wuhan area. The probability formula and the calculation method of reliability index are derived by assuming the probability distribution of settlement rate and using the probability theory of fuzzy event.

Comparisons of egg size,fertilization rate,embryonic development rate,larval settlement rate,larval metamorphosis rate,larval survival rate and postlarval growth among four groups were made.

The article describes the characteristics and tectonic classification of superficial soft soil along Xin-Song highway as well as the method of treatment of fiexible base. Based on nearly 2000 settlement observations through two and oue-half years on the frial lot, the influences of vertical and horizontal unegual settlement, the effect of the crust in the low section embankment and the early stage effect of sand well are analysed and the reasonableness of the design method of gradually variable spacings of sand...

The article describes the characteristics and tectonic classification of superficial soft soil along Xin-Song highway as well as the method of treatment of fiexible base. Based on nearly 2000 settlement observations through two and oue-half years on the frial lot, the influences of vertical and horizontal unegual settlement, the effect of the crust in the low section embankment and the early stage effect of sand well are analysed and the reasonableness of the design method of gradually variable spacings of sand well is also verified. The final settlements have been calculated by using hyperbolic formula and exponential formula, it was pointed out that residual settlement, degree of consolidation and settlement rate can be used to comprehensively evalualuate the stability of the soil base of the highway. The allowable settlement at completion of different sections by taking the construction poriod into consideration has been recommended and a settlementclcalculation method based on cousolidation settlement has been suggested for highway settlement calculation in Shanghai area,

Six commonly used pesticides were sprayed at sublethal concentrations (LC0-13) on common .bean (Phaseolus vulgaris) leaves in the laboratory to test their effect on the predacious mite. The results showed that the pesticides were baneful to the reproduction of P. persimilis. Applications of dicofol at 84 ppm, omethoate at 1 ppm, fenvalerate at 0.2 ppm, cypermethrin at 0.1 ppm, deltamethrin at 0.025 ppm and meothrin at 0.026 ppm resulted in a fecundity reduction of 35.3%, 41.2%, 20.8%, 15.1%, 47.4% and 74.7%...

Applications of dicofol at 84 ppm, omethoate at 1 ppm, fenvalerate at 0.2 ppm, cypermethrin at 0.1 ppm, deltamethrin at 0.025 ppm and meothrin at 0.026 ppm resulted in a fecundity reduction of 35.3%, 41.2%, 20.8%, 15.1%, 47.4% and 74.7% of the predator, respectively, comparing to those in the control treatment. Treatment of bean plant with these pesticides at the sublethal concentrations in the greenhouse further demonstrated harmful effects on the settlement of P. persimilis. The settlement rate of the predator on the plants treated with the forenamed six pesticides at the above concentrations was 48.4%, 50.0%, 25.0%, 11.7%. 3.3%. and 6.7%, respectively, while that in the control was 96.7%. The detrimental impact of the pyrethroids on the settlement of P. persimilis was significantly greater than that of omethoate and dicofol.

The results of settlement analysis, settlement observation and control are included in this paper. The settlement of replaced foundation is relatively small, while the settlement rate is very large. A settlement control is presented in this paper. As a result of observation data analysis, we were succeeded in controlling the residual settlement by adjusting the construction time of concrete pavement. The results from observation after the pavement construction show that the settlement...
