Abstract:After comprehensively discussed the current situation of the nation’s exploration engineering industry and the forward position of foreign countries’ exploration engineering, the differences between the technological levels of inland and international are compared. The general development objects in year 2020 of the exploration engineering are worked out. The specific goals and the key technology which should be put stress on are drawn up.

Abstract:For the purposes of familiarizing science and technology workers with the development situation of new energy resources in foreign countries, thereby promoting them to pay close attention on development prospect of new energy in our county, the development trend, outside and within China, of several kinds of new energy, such as biologic proton energy, biologic diesel oil, solar energy, wind power, geothermy, hydrogen energy and so on, is respectively introduced. Their respective application prospect and potential is analyzed. It is believed that Chinese new energy industry will be launched on “expressway” or “speedway” as soon as possible.

Abstract:According to the basic theory of geophysics and characteristics of gravity field of the earth, the author probes into the source of lateral pressure of pit wall in foundation pit engineering. A new method to calculate the lateral pressure of pit wall in foundation pit engineering has been given. The lateral pressure of pit wall in foundation pit engineering is P=m(θ2-θ1).

Abstract:Analysis of and discussion on critical pre-alarm of safety inspection about retaining and protection of deep foundation excavations are made based on actual specifications and engineering experience.

Abstract:介绍了香港五号干线前期工程石围角至柴湾角段的钻孔灌注桩桩墙施工中的设计及施工工艺；论述了鼓式自配重球齿滚刀钻头及配套的相关机具的结构特点及应用效果。

Abstract:介绍了复合土钉在深圳安诚置业发展有限公司办公综合楼基坑支护中的应用。对支护设计、施工工艺、监测等进行了论述。

Abstract:桩侧和桩端后压浆应在钻孔灌注桩成桩后3~7天进行。压浆过程中应控制灌浆压力以避免过分压裂土层。压浆量是影响后压浆质量和提高单桩承载力的关键因素。在渗透性小的地层后压浆机理主要是压密注浆，在渗透性大的地层的后压浆机理主要是渗透注浆。通过桩侧和桩端后压浆，瑞通广场钻孔灌注桩单桩承载力特征值提高了67%。

Abstract:简要介绍了云南省大理至保山高速公路K376+140~460段公路路槽开挖，诱发古滑坡体复活的牵引式碎石土滑坡的防治设计与施工情况。在认真分析工程地质的基础上，作出治理设计方案并施工，最终通过现场实验监测及雨季的考验，工程达到预期效果。

Abstract:针对目前固结灌浆材料所存在的问题以及地质灾害治理、重大工程的紧急抢修、江河堤坝防渗加固的需要，研制了一种高强无公害、无收缩、凝固时间可调(控)、高流动性、高抗渗的工程灌浆新材料。

Abstract:The paper brings forward a sort of pressure sensor that made of stretch film piece and slightly bend concoct construct, it use OTDR distributing optical fiber pressure sensor. It roundly expatiate theory of single slightly bend optical fiber’s pressure sensor and system of measure rock body thrust, analyses and demarcate delicacy and space distinguish. The optical fiber pressure sensor have characteristic of high delicacy and pace distinguish and finer practicability, passed field test.

Abstract:A new computerized method to quickly calculate the rock drillability with logging data is introduced. The new method can predict rock drillability accurately and draw the continuous section of rock drillability quickly. Indoors micro-bit testing and its application in Jianghan oil field verify that the result of the software is accurate, so it can be put into use in oil field.

Abstract:鄂尔多斯北部塔巴庙工区在钻井施工过程中发生了大量的刺、断、粘钻具事故，极大地影响了该区块的勘探开发速度，也是影响钻井效率提高的瓶颈，通过对钻具失效事故进行分类统计，分析了钻具失效事故的原因，提出预防或减少钻具失效的改进措施。

Abstract:井中电视为指导成井修井提供了先进的手段，从而提高了测井及成井修井的成功率和效率。通过实例介绍了井中电视在成井修井中的应用效果。

Abstract:Boundary conditions of radial slip casting, grouting materials and grouting techniques are researched taking the high pressure water bearing zone within Yuanliangshan tunnel as a studying target. The research results were applied in the actual construction situations and a quite good result was achieved. As the amount of design and construction of underground engineering goes up, the radial slip casting technology will be applied more widely.
