摘要結合山東省南水北調濟平乾渠工程襯砌試驗段施工情況，著重從地基處理、墊層料鋪設、混凝土原材料質量、混凝土澆築、成型混凝土割縫及養護幾個方面分析了機械化襯砌混凝土板裂縫產生的主要原因，並針對性地提出了預防及控制措施。Since the shallow depth excavation is the main factor to cause ground settlement in shenzhen subway tunnel, this paper discusses some corresponding countermeasures including the improvement of ground property, appropriate draining of groundwater, scheduled excavation depth and width, etc, to control strata distortion and surface settlement, and argues that these measures are expected to effectively control surface settlement while constructing city subway in soft ground excavation
摘要針對深圳地鐵淺埋暗挖隧道施工中影響地表下降及地層變形的因素，提出了遵循「十八字」原則、改善土體特性、適度排放地下水、根據地層條件選擇施工方法、增大左右線隧道開挖面的距離、合理確定開挖進尺、提高施工效率、加強初期支護、及時施作二次襯砌等對策。Responsible for or taking part in the research projects which have been spread and received scientific and technological progress rewards, such as " prestressed strengthening technology ", " oil - proof of the composite flooring for multi - storied industrial building ", " the strengthening technology with shotcrete ", " the strengthening technology with carbon fiber material ", " the diagnosis and treatment for leakage of exterior wall ", " the testing and identifying technology of energy - saving building ", " the testing technology of the actual strength of the bonding mortar in masonry structure "
負責和參加了"預應力加固技術" 、 "多層工業廠房抗油滲復合樓地面技術" 、 "噴射混凝土加固技術" 、 "碳纖維加固技術" 、 "外墻滲漏診治技術" 、 "節能建築檢測鑒定技術" 、 "砌體結構砌築砂漿實際強度檢測鑒定技術"等多項科研成果，並得到推廣應用和獲得科技進步獎。The study lies in following aspects : 1 ) a great number of experiments on sfrc are carried out to obtain the basic data of sfrc energy properties, which are the fundamental parts of further study. 2 ) a probability analysis based on statistical theory is done to all the experiment data. in the end, energy criterion for sfrc associated with security criterion are calculated and listed for future use
本文主要針對鋼纖維噴射混凝土在單層隧道襯砌中的應用進行了研究，內容包括以下幾個方面： 1 ）進行了大量的鋼纖維混凝土標準試件試驗，試驗的成果和數據為研究鋼纖維混凝土的能量特徵提供了事實依據和參考； 2 ）運用概率統計方法對鋼纖維混凝土的指標進行了可靠性分析，得出了實際可以接受的保證率下的鋼纖維混凝土能量指標； 3 ）通過合理的假設和簡化，研究了鋼纖維混凝土構件在破壞過程中的能量耗散機理。And it can be concluded that cracks on top floor ' s walls are caused by the temperature difference between floor or wall ' s inner and outer surface and the temperature difference between floor and walls. if the floor and wall ' s thermal resistance is appropriate, the cracks issue on cscbb can be solved
分析表明，砌體建築頂層墻體的裂縫主要是墻體、屋面板內外表面溫度差異和屋面板、墻體之間的溫度差異所致，因此如果墻體和屋面的保溫隔熱措施合適，砌體建築的溫度裂縫問題是可以解決的。The forming - nucleus drive power could form numerous little crystal nucleus under natural melting temperature. the formation of tic particles in the melt could be divided into two phases which was forming - nucleus and growth. the forming mechanism of tic was : melting ti first surrounded c, then ti melting in the alloy and c formed a complicated reaction mesosphere on the carbon surface
根據熱力學及動力學分析，認為在碳顆粒界面處tic的形核率很高，形核驅動力足以在正常的熔煉溫度下形成眾多的小晶核；熔體中tic顆粒的合成可分為形核與長大兩個階段，其形核機制為：首先活性ti原子包圍c ，溶入合金中的ti與c在碳表面形成一復雜反應中間層，隨著反應進行， ti和c顆粒不斷減少，生成的tic不斷彌散分佈於熔體中；其長大過程伴隨著tic顆粒的相互堆砌、聚集和形態規則化。分享友人
