Microclimate Characteristics of Plastic Greenhouse in the Summer in Southern Area of Guangxi;

Analysis on microclimate characteristic in sring of six-span plastic greenhouse in southern areas of Guangxi province;

The application of pre-casting technology through advanced installed pipe shed in portal section construction of highway tunnel in fault-rupture zone;

After studied the Liuqiao fault fracture zone water yield property and transmissibility,pipe shed support and advance grouting reinforced engineering were adopted before the crossheading cut through the fault,meanwhile a series of tried and true driving and supporting measures taken on to insure the-380 crossheading cutting through the fault safely.

Principle of pipe shed for box culvert with large cross-section is analyzed,and bearing function of pipe shed is proved by actual project.

Based on the analyses of the core description,the petrology characteristic and section structure and taking Well HZ25-3-2 as a representative,the authors divide the sedimentary systems into two types,that is,the marine facies fluvial-dominated delta and continental shelf,discuss the essential features of the tow sedimentary systems,and then further recognize two.

Later Paleozoic sedimentary system has 5 sedimentary systems: barrier lagoon - tidal flat system, carbonate continental shelf system, delta system, peat swamp system and river system.
