  1. In this paper, combined with the research project " study on the design, construction and quality monitoring of foundations in karst and mined - out regions along tanshao highway " financed by the department of communication of hunan province, a deep analysis has been made to find out the factors influencing the safe thickness of bearing stratum under the pile tip in karst region. three simplified models are set up to calculate the safe thickness, from which empirical calculation formulas are deduced. and a few important conclusions drawn from the discussion can be used to guide engineering practice, which are also valuable materials for the revision of current criterions later

    本文結合湖南省交通廳「潭邵高速公路巖溶及采區路、橋基礎設計施工與質監控方法研究」研究課題,以潭邵高速公路為工程依託,通過深入分析巖溶區基樁樁端持力層安全厚度的影響因素,提出了樁端持力層安全厚度計算的三類簡化模型,以此為基礎,推導出了樁端持力層厚度計算公式,並通過討論得到了可用於導工程實踐的幾點重要結論,可供今後規范的修改參考;本文對巖溶地區的特殊情況,提出了巖溶區樁基設計方法及具體設計步驟,並借鑒國內外巖溶區樁基的成功經驗,提出了巖溶區樁基設計處理幾種特殊方法,可供同類工程借鑒;另外,本文通過具體的工程實踐,系統總結了巖溶區樁基施工技術及遇問題的處理方法。

  3. On the basis of the calculating of complexity ( c value ) and combination entropy ( h value ) from the numerical method of geoanomaly analysis, logged signals data ( spontaneous potential, acoustic slowness, spontaneous gamma ray and electrical resistivity ) and seismic data ( amplitude, frequency, phase, etc. ) are processed after regularization of data obtained from linqing basin of shengli oil field. many types of geoanomalies obtained from the computation are analyzed so the spacial variation rules of them can be discovered. then the oil regions can be predicted by this method

    本文創新性地將地質異概念引入油氣勘探領域,以地質異理論為導,以勝利油田臨清坳陷油氣地質異預測研究為例,對我國陸相含油氣盆地的規測、測試和解釋數據,如與地震相關的數據(振幅、頻率、吸收系數、層速度等) 、與測井相關的數據(自然電位、聲波、視電阻率、自然伽馬等)等,提取不同數據類型的地質異以及異組合特徵,通過對這些參數的綜合研究分析其間變化規律,系統地建立有效預測油氣藏的新技術和新方法,進而達到區域油氣資源預測的研究目的。
