Abstract:针对目前我国江河堤坝防渗加固技术的现状和存在问题，阐述了技术应用和发展现状、技术分类和参数选择、高喷防渗墙设计参数、高喷钻具的研制开发、喷嘴的设计优选、三管旋喷注浆参数的试验探索、防渗连续墙质量检查等方面的有关问题。

Abstract:The technical characteristics and parameters of multi-medium reverse circulation (RC) drilling techniques are analyzed. The trial-manufacture, test-research, application and effects also are introduced. Testing proved that RC drilling has the advantages of higher drilling efficiency, better geological effects and distinguishing formations in time. The success of the RC drilling technique will provide a new drilling method for geological prospecting and have potential application market in China.

Abstract:The Single-tube High Pressure Grouting Method is quite simple, but the diameter of pile formed by this method is smaller. The improvement of the Single-tube High Pressure Grouting Method, how to amplify the diameter of the chemical churning pile, the craft of plug reinforcement cage in chemical churning pile and the mechanism of this method are deal with in this paper.

Abstract:The methods of geo-technical investigation and surveying on the loosen soils is researched systematically, based on some of major projects in the southeast Tibet, which is instructive to building in Tibet.

Abstract:煤矿的煤仓在施工时由于受当时技术条件和环境的限制，煤仓的底部基础基本都是整板基础形式，并没有设计桩基础。由于煤仓储煤量较大，经长期使用及煤仓外堆煤较多的影响，多数煤仓或多或少出现倾斜现象。针对此种情况，采用地面注浆进行加固治理煤仓倾斜。通过对其方案设计、施工方法、注浆效果检查分析，论证了地面注浆在加固治理煤仓倾斜问题中的必要性和可靠性。

Abstract:通过对中南石油局第四普查大队第15栋住宅楼墙面开裂的原因分析，介绍了采用静压渗透注浆结合压密注浆技术对地基土进行加固处理的情况和良好的效果，并提出了对类似工程处理的几点看法。

Abstract:Based on characteristics of supporting work for deep excavation in metro, an index system for supporting version was established. The weighting of index was set up with hierarchy analysis. A single level fuzzy evaluation model was formed with fuzzy mathematical method. The uncertainty of the index factors was quantified. A case study showed that fuzzy comprehensive evaluation method was reasonable and effective, and can be referred to practical engineering.

Abstract:Being dead against the problems existing in sliding bearing and rolling bearing of cone roller bits, the author of this paper put forward a sliding-rolling bear used in roller bits. The finite element analyses, analogue testing, and practice testing were conducted. The results of the testing showed that the sliding-rolling compound bearing is a new advanced and creative kind of bearing.

Abstract:To counter the drilling technology, bore well structure and mud system, Casson rheology pattern was optimized and circulation Pressure Drop of CCSD-1 well in different depth was calculated by applying mathematical statistics andregression analysis with 2000m cored drilling practice and data collection of drilling fluid performance testing. Circulation Pressure Drop of PDM and Hydro-percussive hammer for rotary-type double tube core barrel tool were respectively tested. Pressure loss distribution of circulation fluid in each pipe passage was decided in conclusion.
