Hydrochemical data of karstic water in Jinan, Shandong Province, were interpretated with methods of ion ratios, principal component analysis, and correlation analysis, in order to explore the hydrochemical characteristics and variation of the groundwater. Generally, groundwater is oversaturated with calcite and dolomite (SI>0), and undersaturated with gypsum (SI<0). Our results indicate that the hydrochemistry of groundwater in Jinan is controlled by both water-rock interaction and anthropogenic activities. Dissolution of carbonates contributes main source of chemical components of groundwater, while anthropogenic activities cause variation of hydrochemical components which differ spatially. Hydrochemical components of groundwater in the western suburb and southern recharge zone are primarily influenced by the dissolution of carbonates, groundwater in the eastern suburb and the central city is overlapped with effects of human activities. Groundwater in the western suburb and southern recharge zone is better in quality than that in the eastern suburb and central city because of relatively natural environment in the western suburb.

In China, Drinking-water type fluorosis is distributed widely. Based on field investigation and water samples collection, fluorine distribution characters of groundwater and their influencing factors in Pingdu of Shandong Province were studied in this paper. The results show that fluorine concentration of groundwater in Pingdu ranged from 0.2 mg/L to 18.6 mg/L and high fluorine groundwater is mainly distributed in Low-lying areas, southwestern of Pingdu. High fluorine groundwater is affected by many factors, among which high fluorine strata is the foundation of high fluorine groundwater, and the following three factors are important for fluorine distribution: regional landform, groundwater recharge, run-off, discharge and hydro-geochemistry. Strata with high fluorine in the northeastern of Pingdu were leached by precipitation and flowed into southwestern low-lying areas, where fluorine was cumulated and enriched for groundwater discharged difficultly as well as suitable hydro-geochemistry condition.

Deriving motion equation of flap valve with the energy method, calculating and analyzing the opening Angle and impact force of different forms of installation (free rollover, free suspended, covers), different valve pages (single-leaf and double-leaf) and different materials (steel and composite materials) with the example of BaiLizhou pumping station. Under the same conditions, the results show that: for single-block flap valve of different installation, opening angle of free rollover flap valve is bigger than free suspended flap valve at 22°, and bigger than covers flap valve at 12°, impact force of three installation forms flap valve is close. For different valve pages, opening angle of double-leaf flap valve is slightly larger than the single- leaf, impact force of free rollover double-leaf flap valve is 42% of the single-leaf, and covers double-leaf flap valve is 49% of the single-leaf. Comparing different materials, opening angle of free rollover composite flap valve is 4% bigger than the steel flap valve, its impact force is 9.6% smaller than steel flap valve, and opening angle of free suspended composite flap valve and covers composite flap valve is 10%~15% bigger than their steel flap valve, impact force of free suspended composite flap valve is 39.5% smaller than the steel flap valve, and covers composite flap valve is 28.5% smaller than the steel flap valve. This shows that, for the hydraulic performance, free rollover and composite material flap valve is worthy of praising.

Conventional triaxial compression test is conducted to research the intact loess structural in Yang ling, Shaanxi province. We, based on the Duncan-Chang hyperbolic model, improve the structural parameters proposed by Shao Sheng-jun. It could avoid the tedious and inaccuracy when computes parameters in the artificial interpolation way, and furthermore overcomes the shortcoming of no meaning as ε1=0 and ε1=15%.Then on the basis of the above work, analyses the influence law of consolidate pressure and water content on structural characteristic of loess. The results show that: the structural parameters of unsaturated intact loess firstly decrease with strain increasing and then remain at a stable level. Under the same water content, the smaller the consolidate pressure, the greater the structural parameters and under the same consolidate pressure, the lower water content, the greater the structural parameters. Finally, after introduced the structural parameters into stress-strain relationship of the intact loess, better normalization of the stress strain curve is got, which shows that the structural parameters are reasonable and reliable.
