Abstract:This paper firstly introduces the deep excavation’s engineering situation, geological and hydro-geological conditions of Wuhan University’s Science and Technology Incubator Building, and mainly introduces design train of thoughts of choosing different timbering precepts according to field’s circumjacent condition. And then, it presents processing method to control of ground water. Otherwise, it introduces requirements of construction monitor and measure of emergency treatment. Monitor and measure real time was carried out, which was designed to ensure construction process and circumjacent buildings all right.

Abstract:The construction technology of deep foundation pit support in fine sands in Hangzhou was discussed. The foundation pit is the first one which used flexible wave pattern joints to connect diaphragm wall in fine sands. The success of the project provided the practice experiences for the similar deep foundation pit support. It is significant to Subway building in Hangzhou.

Abstract:Mechanism of stratum pressure casting in deep foundation pit was introduced, taking the foundation construction of a hospital building. The determined values of several main parameters during design were discussed. The method for pressure casting is pointed out.

Abstract:结合四川某桥基础加固处理的工程实践，对树根桩进行加固桥涵地基的优点、设计计算要点、施工工艺和施工质量控制措施等方面进行了阐述。

Abstract:The sewage modification project in Taicang City of Jiangsu required high accuracy of pipeline laying. The pipes were double wall PE Pipes. Their strength is low. It is a challenge to current trechless technology. The difficulties and design main points of the project were introduced. Meanwhile the problems encountered during construction were analyzed.

Abstract:The relative calculation model was selected to analyze the stability of high upward slope in tunnel, taking comprehensive consideration of rock types, structure face development situation, weathering and other facts. Jetting concrete, hanging net with jetting cement, radioactive installation of anchorage and other alternatives were provided to protect the slope, considering landscape.

Abstract:通过对陕西某黄土质边坡的支护，概述了锚杆喷射混凝土的设计计算及施工技术应用，以及工程完成后的工程质量检验监测。

Abstract:Under the guidance of rock broken theory of flat base roller bit and conventional cone base wing shaped bits, the drilling mechanism of flat base roller bits in big deviation was analyzed. The key structure and main parameters of modified cone base roller bit were designed. The flat base roller bit was modified into cone base roller bit. The modified bits were used in project and good results were gained.

Abstract:There are mainly three geothermal reservoir of fissure karst type, pore-type and fissure type in Shandong region .In this paper the drilling techniques of three types are researched according to three geothermal reservoir models and the drilling techniques of geothermal well in this region are also researched.

Abstract:During the construction of one Myanmar ship yard dry dock project，a part of wall of wells for pumping test collapsed. The local instability reasons comprise ground water dynamical action, compaction effect of pile foundation, pressure grouting. After taking some measures, including making using of ground water dynamical action, improving slurry performance, releasing the compaction effect of pile foundation and so on, there was no local instability happened, and the quality of wells was testified very good by pumping test.

Abstract:The general geological situation and drilling technology of geothermal well in Grand Canyon were introduced. The causes of small water output from the well which is located in limestone were analyzed. The measurement for increasing water output was provided and applied in practice. Two measurements for increasing water output were compared. The suggestions to increase water output in similar well was made.

Abstract:在总结多项工程实践和查阅大量相关资料基础上，以倒垂孔为例，全面系统地介绍了基岩中高精度钻孔施工各项技术和最新工艺。

Abstract:After analyses and research on material quality and physico-chemical function of processed〖KG*2〗workpiece, honing technique, ablation mechanism, and having made a lot of tests and practices, a new type of binding agent, diamond honing oilstone, was developed. The manufacture method and the technique formula were summarized out. The honing technology will be developed and the economic efficiency of diamond products in our country will be promoted as the product is developed and popularized.

Abstract:The characteristic, development and research of artificial freezing technology were presented. The freezing technology application of horizontal freezing and vertical freezing was discussed. Some disadvantage of artificial freezing technology in theory research and engineering management and its development direction were indicated.
