With metal fatigue in material mechanics, this paper deduces the limestone fatigue curve of longmen grottoes by means of marble s one within the error permission. by the experiment elects the crucial factors of current vibration environment in longmen grottoes, the author contrasts the result of the experiment with its fatigue curve referred above and analyses the fatigue effect of longmen grottoes. finally, it is pointed out that after longmen grottoes have being suffered weathering and water - erosion more than 1500 years, the vibration environment is becoming an crucial factor leads to fatigue effect, especially in those weak surface carvings just like the crossings of several rifts, serious weathering places, etc
借鑒材料力學中金屬疲勞破壞的研究手段，在誤差允許范圍內用大理巖疲勞曲線推導出門石窟石灰巖疲勞曲線。通過對石窟實際振動環境中典型要素的抽取和振動試驗，將試驗結果與疲勞曲線進行對比，分析了門石窟的疲勞破壞效應。文章指出，在經歷了1500多年的風化和流水溶蝕后，振動環境已成為導致門石窟某些薄弱點如多條裂隙交叉點嚴重風化酥解的壁面雕刻品等產生疲勞破壞的重要誘發因素。The safety of ash dam situated in earthquake regions has always been paid great attentions by designers. because of the big void ratio and easy liquefaction of fly ash, it is of great significance to investigate the seismic stability of such ash dam with the height over 100m, as sanmenxia longgou ash dam
粉煤灰具有孔隙比大、易液化等特點，建在高地震烈度區的三門峽龍溝灰壩已超過百米，在國內尚無先例，其抗震安全性與施工措施、設計指標的分析、研究具有深遠的科學意義與廣闊的應用前景。Abstract : this paper, giving the case history of two large - s ized docks built on complex limestones with cavities, grooves, troughsond develo ped fissures in dalian area, presents the construction techniques adopted in the construction of the docks and makes analyses and co mparison between the advantages and disadvantages of the techniques
文摘:本文通過同在大連地區溶洞、溶溝、溶槽和裂隙發育的復雜石灰巖地質條件下所建造的兩座大型船塢的實例，介紹了所採用的不同的施工工藝，並對其優缺點進行了相對的分析和比較。Through much analysis of laboratory experiments, this paper reach the conclusion that aggregate gradation, degree of compaction, water cement ratio and magnitude of cement are the main factors that influence the coefficient of permeability and the compressive resilience modulus of high air void cement - stabilized crushed stone mixture
本文通過大量的室內試驗發現，集料級配組成、壓實度、水灰比和水泥用量是影響大孔隙水泥穩定碎石混合料滲透系數和抗壓回彈模量的主要因素。Through changing and improving the traditionally adopted technology and equipment in compacted lime - soil pile foundation, so as to eliminate weak collapsibility of loess in luoyang and increase the strength of foundation, the authors present formulas to compute the average dry density and void ratio after ground treatment and demonstrate the feasibility of these formulas through practical project cases
摘要基於洛陽地區次生黃土的弱濕陷性，對傳統的灰土擠密樁施工工藝和設備進行改進，達到消除濕陷性，提高地基承載力的目的，並且推導出地基處理前後干密度和孔隙比隨置換率變化的關系，以工程實例證明該公式的可行性，避免布樁型式的經驗性和處理結果的不確定性。分享友人
