结合常州恐龙园基坑工程,基于预应力板桩支护方案,选取几何相似比1∶30,开展基坑土方开挖,坡顶超载共6种工况相似材料模型试验。研究表明:基于9 m深粘土与砂性土互层基坑,桩顶水平位移、土体水平位移及桩身弯矩随着开挖深度和坡顶超载的增大而增大,开挖到预设深度和超载逐渐增大时,基坑变形较大;开挖完成后正负向最大弯矩出现在开挖深度上下1/3处;在3种桩距中,支护结构桩距过大会出现土体绕流,桩距过小又会增加施工成本,因此在考虑基坑变形控制、成本控制的情况下,宜选择桩距为4倍单桩宽度。通过理正软件进行各工况计算,验证模型试验结果正确性。

为深入研究双排空心管桩作为新型支护结构在基坑工程中的变位特性,结合常州恐龙园中心广场基坑工程,选取几何相似比1∶30,完成6种工况下室内模型试验。研究表明:开挖阶段,桩后土体水平位移随入土深度逐渐增大,底部水平位移是顶部的4.2倍;加载阶段,桩后土体水平位移随入土深度先增大后减小,峰值出现在深度为3m处,底部水平位移是顶部的2.5倍。在各工况中,超载时基坑顶部水平位移是开挖的8倍,建议对基坑周边堆载情况下的桩体整体提高配筋要求,同时在施工中做好变形监测工作。前后排桩区别设计:前排桩设计强度高于后排桩;前排桩的开挖面附近和后排桩0.44h0(h0为开挖深度)的横截面提高配筋要求。建议双排空心管桩桩距采用较小的桩距,排距采用5倍桩径。理正计算所得的结果与模型试验基本一致,验证了模型试验的正确性。

Cement and resin were designed as mixed cementitious materials to study the smart aggregate(SA)of smart *** fiber(CF)and surfactant were taken into consideration to adjust the mechanical and electrical properties of smart aggregate(SA)in this *** experimental results indicate that the flexibility and mechanical properties of SA can be improved by using such mixed cementitious *** is shows that,although the compressive strength and flexural strength can be enhanced effectively by using resin and CF,the electrical conductivity decreases significantly,which is because the water molecules are difficult to penetrate through the mixture materials so the hydration reaction of cement can not fully carry ***,the electrical conductivity can be improved by adding the surfactant,and the strength and mechanical electrical properties can be adjusted effectively by the surfactant.

Naturally occurring molecules derived from higher plants, animals, microorganisms and minerals play an important role in the discovery and development of novel therapeutic agents. The identification of molecular targets is of interest to elucidate the mode of action of these compounds, and it may be employed to set up target-based assays and allow structure-activity relationship studies to guide medicinal chemistry efforts toward lead optimization. In recent years, plant-derived natural compounds possessing potential anti-tumor activities have been garnering much interest and efforts are underway to identify their molecular targets. Here, we attempt to summarize the discoveries of several natural compounds with activities against hematological malignancies, such as adenanthin, oridonin, gambogic acid and wogonoside, the identification of their targets, and their modes of actions.
