根据上海地区区域资料地下水主要有浅部粘性土、粉性土层中的潜水，部分地区

According to regional data of groundwater in Shanghai are mainly shallow clay, silty soil diving, deep silt in some areas, sand layer (micro) confined water. According to the temperature information, groundwater, by the depth in the range of impact of temperature changes 4m, 4m or less stable temperature, generally 16 ~ 18 ℃.

According to the regional data of Shanghai area, groundwater mainly has shallow sticky soil, powder soil layer diving, some areas of deep powder soil, sand layer (micro) pressurized water. According to the relevant information, the temperature of groundwater, buried depth in the range of 4m by the temperature changes, 4m below the water temperature is more stable, generally 16 to 18 degrees C.

According to the regional data of Shanghai, groundwater mainly includes phreatic water in the shallow clayey soil and silty soil layer, and (micro) confined water in the deep silty soil and sandy soil layer in some areas. According to relevant data, the temperature and burial depth of groundwater are affected by the temperature change within 4m, and the water temperature below 4m is relatively stable, generally 16-18 ℃.<br>
