中文拼音 [pǔtōngzhuāntǔ]
普通磚土
英文
common brick clay-
Buildings made of air blocks react sensitively to factors effecting crack. under same conditions, the blockworks of building crack worse than wall made of clay bricks and crack types are also more complicate. purpose of the thesis : from the reasons of crack, crack development, domestic and overseas theories on crack, i make a deep research on crack
砌塊墻體與普通粘土磚墻體開裂的現象有相當的一致性，又有其特殊性，由於砌塊建築對影響開裂的因素反應更為敏感，在相同情況下，砌塊建築墻體開裂的程度比粘土磚墻體要嚴重，裂縫的類型也比較復雜。Concrete common bricks and decorative bricks
混凝土普通磚和裝飾磚The productions include : 1. the investigation of crackss of masonry structures, the characteristic and the reason on cracks of wall ; 2. the limited element analysis about datum of brick - wall the relation between the maximal stress in wall and the relative sedimentation of foundations, the relation between the cracks form in wall and inner stress, the validity of limited element mode ; 3. the limited element analysis about the relative sedimentation of foundations, the influence of ratio of length and height, foundations rigidity, groundsill rigidity on the inner stress in wall ; 4. the limited element analysis about the influence of temperature on wall cracks and the influence of space between extension cracks, difference in temperature on the inner stress in wall ; 5. the analysis about the cracks rule because of temperature, the contrast between the result and the simulant result ; 6. the study about the influence of cracks of masonry structures because of constriction stress, the experience of dealing with constriction cracks in the domestic and the foreign ; 7. the advice of avoiding cracks because of the asymmetric sedimentation temperature, constringency in design and construction
本研究結合實際工程中的砌塊建築普遍存在的裂縫問題，參照磚墻裂縫調查研究的成果，針對我省的砌塊應用狀況，進行了充分的調研，並查閱大量的文獻資料，總結了砌塊建築墻體裂縫的特點和規律，通過對溫度裂縫、沉降裂縫的有限元分析和經驗公式的對比，深入的探討了墻體開裂的影響因素，結合各地實際工程經驗，在對混凝土砌塊墻體在材料、設計、施工等方面進行系統的理論分析、綜合研究的基礎上，給出開裂的防治方法，促進混凝土砌塊在我省的推廣應用，為相關規范的編制提供理論依據和經驗分析，主要研究成果有： 1砌塊砌體開裂的調查研究，墻體開裂的特點和原因總結； 2有限元分析磚墻實測數據，揭示了墻體內最大主應力和地基相對沉降量的關系及墻體開裂形態與內部應力的聯系，並且驗證了有限元模型的有效性； 3
