An Experimental Investigation on the Stress-strain and Permeability of Chemically Grouted Sands
( Gailing Zhang ),( Yaping Wang ) 대한지질공학회 2019 대한지질공학회 학술발표회논문집 Vol.2019 No.2
This paper present an experimental investigation on the stress-strain relationship and permeability of chemically grouted sands during failure process in a triaxial test. The influence of confining pressures, chemical grouts contents, curing time and temperature on permeability and stress-strain characteristics of chemically grouted sands were investigated in the laboratory tests. Moreover, the pore characteristics and the relationship between permeability and deformation failure are also studied by analyzing the results of mercury intrusion porosimetry (MIP) and CT test. The experiment results show that the influence of slurry content on the permeability is obvious, when the slurry content reaches a certain threshold value, the permeability reaches the minimum value. The permeability of chemical grouting sands changed greatly under different confining pressures. Different curing ages have influence on the permeability. When the curing temperature is low, the variation of the permeability is significantly affected by the temperature. When the temperature is high, the influence of the temperature on the permeability coefficient decreases. The effect of strain on permeability coefficient is much smaller than that of confining pressure, slurry content, curing time, curing temperature and other factors. The pores of chemically grouted sand are mainly superpore and macropore with few micropores. The actual case shows that the chemically grouted mass has good durability.

Objective: Limited evidence exists concerning whether combined pharmacotherapy is more effective than monotherapy for increased smoking abstinence and post-cessation weight gain prevention. This research investigated the effect of combined pharmacotherapy on smoking abstinence and post-cessation weight change. Methods: A meta-analytic review of Randomized Controlled Trials (RCTs) published between January 1990 and July 2016 was conducted across PubMed, International Pharmaceutical Abstracts, Web of Science, and Cochrane Library. Aggregate fixed effects were estimated for continuous abstinence and mean post-cessation weight change. Keyword search terms included: “smoking cessation,” “naltrexone”, “varenicline”, and “bupropion”. Results: Eight RCTs with 2,513 participants were included. Aggregate fixed effect estimates revealed an increase in continuous smoking abstinence (OR = 1.81, p < .001) and mean decrease in post-cessation weight change (-.15 kg, p = .001). Decreased weight change was observed at 6-8 weeks follow-up (-.14 kg, p = .02). Increased mean weight change was observed among varenicline plus nicotine patch abstainers (.21 kg, p = .01), whereas bupropion plus NRT pharmacotherapies showed decreased mean weight change (-.15 kg, p = .01). Conclusion: Combination pharmacotherapy generates increased smoking abstinence and small short-term post-cessation weight change among abstainers, particularly among bupropion plus NRT when compared against varenicline plus nicotine patch.
