The analyzing aboved is made from earthquake's space distributing, periodicity, migration phenomenon, repetition, strength, frequency, b value etc., according to data of earthquake station net in Shaanxi Province and microseisms station net watching results in Xi'an area. 3 group faults which are NEE, NW and EW direction control earthquake activities in Guanzhong area. Epicenter depth mostly is 5-25km and in shallow-focus earthquake. Earthquake in east area of Guanzhong was stronger and weaker in the West in history. Fen-Wei earthquake belt showed more activity. Microseisms and small seisms is main movement in recent earthquake, it has 8-10years' period of movement and show the trend that they are strong in the West but weaker in the East. And frequency and biggest magnitude of earthquake is supplement each other. In next years earthquake frequency will lessen but strength enhance, about M4. It presumes there is earthquake climax period in Guanzhong area in 2040 and M5-6 earthquake is happened at that time.

本文在对关中地区区域构造及重磁异常特征的分析基础上，根据陕西省地震台网监测资料及西安地区微地震台网监测成果，从地震的空间分布特征、周期性、迁移现象、重复性、强度、频度、b值分析等方面，对区域地震活动特征、关中地区地震活动规律进行了分析研究，关中地区地震活动主要受北东—北东东向、北西向、东西向三组方向的断裂控制，震源深度多为5—25公里，均属浅源地震，历史地震表现为东强西弱，东部的汾渭地震带表现出较强的地震活动性，近代地震活动主要以微震或小震为主，存在着8—10年的活动周期，近期表现出西强东弱的趋势，地震的频度与地震最大震级呈互补关系，未来的几年间，地震频度会有所减少，强度会增大，将有可能发生4级左右的地震，推测在2040年左右，关中地区将进入地震高潮期，届时将可能有5—6级左右的地震发生。

Aiming at these factors,our main ameliorative measures are:as following:adopting " three-high rates " composition,in a specific way,three rates should choose KH:0.88-0.92,SM:2.6-2.8,IM:1.6-1.8,and controlling the content of R2O,SO3,this method can insure that the content of silicate mineral is higher than 77%,especially the content of C3S is lower than 55%,so it can compensate for insufficient of descending of cement strength resulted by inactive component after implementing the checking method of ISO cement strength.

针对这些因素的主要改进措施为：采用&三高&配方，即三率值宜选择为KH0.88～0.92、SM2.6～2.8、IM1.6～1.8，并控制好R_2O、SO_3含量，以此保证水泥中的活性组分即硅酸盐矿物的含量≥77％，特别是C_3S含量不能低于55％，这样就能弥补因实施ISO强度检验方法后，水泥中非活性组分导致强度下降的不足。
