摘　　要：新的高温高压实验研究证实莺歌海盆地泥底辟构造是在热动力作用下形成和演化的，在0－300℃条件下，饱和水泥质实验材料（高岭土）产生了0－1500×10^-6应变量，干的中粒度砂质材料的应变量仅仅为0－150×10^-6，饱和水中粒度砂质材料的应变量大约为0－590×10^-6。新的实验结果证明，热动力可以产生热应变，热能可以转换为应变能，高压对于泥底辟构造的形成和演化起到了促进作用。New high T and high P experimental results prove that the mud diapirs in Yinggehai Basin, South China Sea have been formed and evoluted by thermodynamic effects. Under conditions of 0-300℃, saturated mud materials (Kaoline)show strain 0-1500- 10-6, dry sand materials of middle grain size only with strain 0-150× 10-6>and same saturated sand materials with about strain 0-590×10-6. New experimental results show that thermodynamic effects could cause thermal strain, and thermal energy could be transformed into strain energy. High P stimulates the formation and evolution of mud diapirs.
