抹面土層
英文
earth lining-
High performance concrete is a very popular key of research in structure material currently. but high performance cement mortar is lack of much attention. in fact, cement mortar and concrete are very close relationship
原因是多方面的，其中一個重要原因是砂漿的應用目前還主要是抹面、找平和砌築，還沒有能夠上升到砂漿是混凝土等結構材料的保護層的高度。3. based on the bond test for 33 concrete specimens and gfrp and bending test for 15 beams strengthening with gfrp, surface preparation of concrete, type of epoxy adhesives, thickness of adhesives, hardening time of adhesives, cure condition after strengthening are considered, and the effect on concrete structures strengthening with gfrp causing by construction behavior was analyzed. 4
根據gfrp片材加固混凝土結構在施工中常涉及到的一些相關因素，如混凝土基層表面處理情況、所選用的粘結劑類型、塗抹粘結劑的厚度、加固的方式以及養護狀況，進行了33個混凝土試件與gfrp片材的剪切粘結試驗，並進行了採用gfrp片材加固的15根混凝土梁的抗彎試驗，分析了與施工性能相關的因素對gfrp片材加固混凝土結構效果的影響。Due to aac ' s unique cell structure and absorbing water propriety, however, there are still many problems, when we adopt ordinary mortar to construct and plasterer ash, such as wall crack, big area of layer of plasterer ash crack and partially hollow drum, even according to present aac technical specifications, for the actual operation craft is so complicated that it is very to guarantee each preface quality
然而，由於加氣混凝土本身特有的多孔結構和吸水特性，採用普通砂漿砌築與抹灰，即使按現行加氣混凝土砌塊施工規定的方法施工，由於實際操作工藝復雜，各工序質量難以保證，依然有墻體開裂，抹灰層大面積龜裂和局部起鼓、空殼、脫落等現象。That is, the partially penetrating sand drain ground is viewed as the double - layered ground, and its consolidation is analyzed with 1 - d consolidation theory, through the transformation from 3 - d consolidation to 1 - d consolidation in the region of sand drain. this can overcome the disadvantage that the excess pore water is discontinuous between the region of sand drain and under - lying soft layer. to the double - layered ground, based on the consolidation mechanism under surcharge, the excess pore water pressure calculation formula is deduced under the condition of multilevel equably loading or unloading, which perfects the consolidation theory
然後，在充分考慮豎井區井阻、塗抹作用以及土體結構損傷破壞對固結影響的基礎上，將未打穿豎井地基合理地轉化為雙層地基，按一維固結理論計算，克服了傳統固結計算方法在豎井處理區與下臥層交界面處存在孔壓間斷的缺點；在此基礎上，從超載預壓法的基本原理出發，分析了雙層地基超載預壓固結、沉降機理，推導了多級等速加、卸載情況下雙層地基的固結計算公式，進一步完善了雙層地基固結理論。分享友人
