为对地面建筑物进行变形控制,需要对冻结法施工冻胀效应进行预测。
2) frozen-heave stress
冻胀应力
1.
Study on early-age frozen-heave stress and the compressive strength rule of the concrete at subzero temperature;
负温混凝土早期冻胀应力与强度发展规律的研究
2.
In this paper,the equipment was designed and developed by ourselves and the regularity of early-age frozen-heave stress of different proportions concrete at subzero temperature was measured(different w/c,anti-freezing agent and air-entraining,fly ash and slag).
自行设计与研制了测量混凝土早期冻胀应力的设备,并通过该设备测量出了不同配比(不同水灰比,掺加防冻剂、引气剂,掺加粉煤灰和矿渣粉)混凝土早期冻后产生冻胀应力的规律;并探讨了不同受冻制度(标养6h后受冻和标养达到其28d强度的30%两种制度)对混凝土抗压强度及抗折强度的影响。
3.
In this paper the equipment was designed and developed by ourselves and early-age frozen-heave stress of control concrete at subzero temperature was measured at the frozen temperature of-5℃,-10℃ and-15℃.
自行设计与研制了测量混凝土早期冻胀应力的设备,通过该设备测量出基准混凝土的温度在-5,-10,-15℃时早期的冻胀应力,进而研究混凝土冻胀应力对混凝土强度及抗冻性能的影响。
3) stress field of frost heave
冻胀应力场
4) die-swell effect
膨胀效应
1.
In this paper, the effect of the jet stretch ratio on the extrusion die-swell effect (Barus effect) of polyacrylonitrile spinning dope and the aggregating structure and properties of the protofibers was systematically analyzed.
研究了凝固负拉伸对聚丙烯腈(PAN)纺丝液的膨胀效应、初生纤维聚集态结构和性能的影响,初步揭示了膨胀效应和凝固取向的产生机理及其对初生纤维结构与性能的影响;指出溶剂与水之间的传质速率差是控制初生纤维结构进而控制其性能的最关键因素,它决定了原液细流表面凝固层的组成及结构,而凝固速率反映了凝固层的生长速度。
5) dilatancy effect
剪胀效应
1.
Load transfer method of rock-socketed anchoring rods under pile tip considering dilatancy effect;
基于剪胀效应的桩底嵌岩锚杆荷载传递分析法
补充资料：冻胀丘
冻胀丘是由于地下水受冻结地面和下部多年冻土层的遏阻，在薄弱地带冻结膨胀，使地表变形隆起，称冻胀丘。冰锥是在寒冷季节流出封冻地表和冰面的地下水或河水冻结后形成丘状隆起的冰体。
