As is often the case with men , particularly with those who criticise their fellows severely , prince andrey on meeting a new person , especially one like speransky , whom he knew by reputation , had always a hope of finding in him a full perfection of human qualities 就像人們常有的情形那樣,特別是像那些對別人嚴加指摘的人那樣,安德烈公爵遇見一個新來的人,尤其是遇見這位他所熟知的大名鼎鼎的斯佩蘭斯基時,他總是期待在他身上發(fā)現(xiàn)完美的人格。
When dim pile is applied in work of a freeway project , it is conducted as a study issue , because both the theory about it is not very clear now and also the quality control is hard to demonstrate , in addition , there is a big difference among soft soils in different areas on the distribution , the ingredient of minerals and the physical and mechanical properties 由于這一方法的理論還太完善,施工質量控質也有一定難度,加上不同地區(qū)軟土的土層分布,軟土的礦物成分、物理力學性質等差異性極大,所以每項高速公路工程在采用粉噴樁處理軟基時,都將其列為一項研究課題。
By the check - out , inspection and measurement to start construction the industrial art to this test pile with the examination between stake body mass and bearing power , made sure the stroke reasonable operation method drilling under the dissolved cavern geology term ; the pier foundation loading test expressed the lading and rub the lading that resistance drag a glazing for of relation , and to the borehole cast - in - place concrete pile in the karst terrain deliver with break the mechanism , the characteristic of bearing power , proceeding the spot test job of the full of result ; the test data expresses the stake side friction resistance to rises with a bat batch terminal friction resistance very important function , the of tip of pile resistance drag occupies the proportion very few 通過對本次試樁施工工藝的檢測和樁身質量及承載力的檢驗,確定了沖擊鉆在溶洞地質條件下的合理使用方法;基樁承載實驗表明了荷載與摩擦阻力之間的關系,并對巖溶地區(qū)的嵌巖灌注樁的荷載傳遞和破壞機理、承載力特性,進行了富有成果的現(xiàn)場測試工作;試驗數(shù)據(jù)表明樁側摩阻和支盤端阻起很重要的作用,樁端阻力所占比例甚少。這與設計樁基時的計算模式相差很大,承載力也較設計增加;使用力學數(shù)值分析方法和有限單元法,對鉆孔灌注樁樁端下的巖體強度和結構穩(wěn)定性方面進行模擬計算和定量研究。
Numerous monitoring data have been got through field tests , which makes it possible to know the stress distribution law and deformation character of soft ground reinforced by deep - mixing pile group , and provide useful proof for subsequent researches . at the same tune , precious experiences of design and construction are accumulated . 2 進行了深攪樁復合地基的現(xiàn)場試驗研究,得到了大量的實測資料,掌握了深攪樁大面積加固軟土地基時群樁復合地基的應力分布規(guī)律和變形特性,為后繼理論研究提供了有力的驗證資料,也為設計施工積累了寶貴的經(jīng)驗。
Abstract : based on laboratory test results , a model for predicting the residual deformation of soft clay under impact loading is proposed in this paper , which fits well with other test results . this model , considering several factors which affect the residual deformation such as confining pressure , impact energy and the number of impacting , can be used for the deformation prediction in the treatment of saturated soft clay by the drainage consolidation method of combining static and dynamic loading 文摘:在試驗基礎上建議了一個預測沖擊荷載作用下飽和軟粘土殘余變形的計算模式,該模式考慮了周圍壓力、沖擊能大小、沖擊次數(shù)和沖擊遍數(shù)等幾個因素.對計算模式的驗證表明,預測值與實測值吻合較好.該模型可用于動靜結合排水固結法處理軟基時的變形計算
Conclusions as following have got through test study : ( 1 ) when impact compaction technology is applied to treat collapsible loess subgrade , the effect depth may be treated generally can not override 80 cm and impact compaction pass is optimum at 30 times . ( 2 ) for stratified impact compaction of subgrade , when compactness of each level reaches codeslstandards loose laying depth of 80 cm fits 40 impact compaction pass is the optimum combination of subgrade construction . when average compactness in each level reaches codeslstandards loose laying depth of 80 cm fits 30 impact compaction pass is the optimum combination o ( 3 ) the quality control method may request impact compaction pass as the main control index and at the same time the final division settlement is less than 10 % of total settlement as large area subgrade is constructed 通過試驗研究主要得出如下認識:沖擊壓實技術處理濕陷性黃土地基時,其有效處理深度一般不超過80cm ,沖壓遍數(shù)以30遍左右為宜;對路基分層沖壓,在要求土體中各點壓實度均達到規(guī)范要求時,路基沖壓最佳組合為虛鋪厚度80cm 、沖壓40遍;在只要求土體平均壓實度達到規(guī)范要求時,路基沖壓最佳組合為虛鋪厚度80cm 、沖壓30遍;大面積施工時,質量控制方法可按照在以沖壓遍數(shù)作為主要控制指標的同時,要求最后10遍分計沉降量小于累計沉降量10 ;在施工單位自己購置沖擊壓實機情況下,與傳統(tǒng)施工相比較,沖擊壓實技術是一種既能節(jié)約資金又能大量縮短工期的施工方法。
The results indicate that this method can minish settlement largely , decrease level thrusts on bridge abutment , make the settlements transition , improve the bearing capacity of foundation soil and its economic benefits are notable . the results of field test show that low intensity piles can put into widely use in soft foundation of express way 研究結果表明,采用低強度樁復合地基加固橋頭軟基時,可以采用變樁長、變間距的設計思想,使沉降逐漸過渡,減輕橋頭跳車的危害,并且還可以減小沉降和深層土體水平位移,減小對橋臺及其樁基的水平推力,提高地基承載力。
After saying a few words to pierre of the awful road from the frontiers of poland , of people he had met in switzerland who knew pierre , and of m . dessalle , whom he had brought back from switzerland as a tutor for his son , prince andrey warmly took part again in the conversation about speransky , which had been kept up between the two old gentlemen 安德烈公爵三言兩語地跟皮埃爾談到波蘭邊境后面的一條非常糟糕的道路,他在瑞士遇見幾個認識皮埃爾的人,還談到他從國外帶來一個給兒子當教師的德薩爾先生,然后他在兩個老頭繼續(xù)談論斯佩蘭斯基時又激昂陳詞。
