  3. ( 2 ) taking the geology analysis as main way and combining the pre - test, predicating the tunnel ' s main geology condition ( rock quality, surrounding rock classification, long - wide joint, fault, ground water, crustal stress ), and predicating the main potential disaster ( collapse, breaking water, rockburst, large deformation ) ( 3 ) employing the stress test result and inverse analysis of the stress field, finding out the crustal stress " s distributing rule along the tunnel axes section : the highest crustal stress is 24mpa near the deepest spot, and predicting that the k2 + 260 ~ k3 + 000 likely to be the high crustal stress segment for this tunnel

    通過地質分析、類比分析、監控量測、數值模擬、神經網路等方法，對鷓鴣山隧道潛在的主要地質災害（塌方、涌水、巖爆和大變形）進行了預測預報（ 3 ）在現場地應力測試成果的基礎上，運用數值計算進行應力場反演，基本查明了沿隧道軸線剖面的地應力分佈規律：地應力量級在最大埋深附近達到最大值24mpa ，並預測k2 + 260 k3 + 000段將很可能成為鷓鴣山隧道的高地應力段。 （ 4 ）塌方往往與斷層破碎帶及千枚巖相聯系。
  4. It can lead to not only quick wear and early failure of drill pipe but also the decrease of collapse resistance and burst resistance of casing string, which could cause casing collapse, casing deformation and casing leak, even well bore abandonment

    其直接後果是：鉆柱快速磨損，導致過早失效；套管磨損會降低套管柱的抗擠強度和抗內壓強度，造成套管柱擠毀、變形及泄漏，嚴重時造成全井報廢。
  5. Based on some examples, geologic hazard problems, such as earthquake, geofracture, ground subsidence, collapse, water environmental depravation, landslide, dilapidation, mudrock flow, float sand, piping and yielding soil deformation etc., are summed up generally during the course of development for chinese cities

    以實例的形式，概要總結了中國城市發展過程中存在的地震、地裂縫，地面沉降、塌陷，水環境惡化，滑坡、崩塌、泥石流，流砂、管涌、軟土變形等地質災害問題；根據產生地質災害的動力作用性質，對地質災害進行了分類。
  6. In this paper, in order to solve the difficulties in the rain pipe construction in jianyu road of yulin city, the pipe - pushing technique for the hand - type tool pipe in the sand soil layer has been researched by experiments in which many practice problems were considered such as the movement and deformation of sand soil, the difficulties for the pipe to enter the scheduled work soil, the collapse of excavation surface, the departure of pipe center and the difficulties to correct this departure. by both the calculations for the stabilities of back - supporting soil body and excavation surface and the theoretical analysis on the reasons for the departure ' s producing, some construction techniques were introduced and adopted in this paper which include not only the change and reinforcement to both the back - supporting soil body and the scheduled work soil body but also the settings of pipe cap, lattice and correcting system on the head of the tool pipe

    本文針對榆林市建榆路雨水管道中遇到的技術難題，進行手掘式工具管砂土層頂管法施工技術試驗研究，在研究中考慮砂土層存在的后靠土體移位、變形，工具管難以進入出洞土體，挖掘面易坍塌、管道中心易偏差及難糾偏等問題，通過對后靠土體和挖掘面的穩定計算及偏差產生原因的理論分析，提出並採用后靠土體換填加固，出洞土體換填加固，以及在工具管頭部設置管帽、格柵、糾偏系統等技術措施
  7. The results of the tests show clearly that the carrying capacity of shear - resistance and deformation property and ductility of the masonry walls were increased after being prestressed, and the prestressed walls are forced more uniform and material property can be completely developed. cracks are more slightness and more dense, and will be closed after being unloaded, and the walls will not fall apart with cracks, which indicate that such walls may retain the entirety well and have good resistance of collapse
